What Is the Holy Spirit’s Role in Apologetics?

Christians have long recognized that the Holy Spirit convicts, converts, and convinces unbelievers of the truth “because the Spirit is the truth” (1 John 5:6). In addition, Jesus said of the Holy Spirit, “When he comes, he will convict the world concerning sin and righteousness and judgment” (John 16:8). The Holy Spirit is essential for the effective use of apologetic information toward persuading unbelievers or strengthening believers. What is more, the Holy Spirit’s role is necessary for apologetics to be utilized in evangelism to the lost, the discipleship of believers, and in defending against false teachings. Norman Geisler states, “There is no contradiction between reason and evidence on the one hand and the work of the Holy Spirit on the other.[1]

The Holy Spirit, Apologetics, and Evangelism

One important role of apologetics is evangelism. First Peter 3:15 notes, “Always [be] prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect.” Peter’s mention of “anyone” includes unbelievers. Moreover, the following verse also includes unbelievers by referring to “those who revile your good behavior in Christ” (verse 16). The apostle Peter taught believers to use apologetic methods to persuade unbelievers toward faith in Christ, and did so by complementing communication with a life of conviction. Believers are to have “good behavior” that reflects a life changed by Christ. There are three important aspects of evangelism that are dependent upon the power of the Holy Spirit.

First, the godly lifestyle of the believer is dependent upon the Holy Spirit. Second Peter 1:3 states, “His divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us to his own glory and excellence.” Believers are given many commands to obey; yet the ability to fulfill these commands is based on the divine power of God living in and through the believer.

Second, the ability to effectively share the gospel message with unbelievers is dependent upon the Holy Spirit. The Great Commission teaches believers to make disciples of all nations by going, baptizing, and teaching others the good news of Jesus as Lord (Matthew 28:18-20).

Though any person can read the words of the New Testament, the Holy Spirit is necessary to effectively bring the gospel message to an unbeliever who will hear, believe, and receive that message. In Romans 10:14-15, Paul noted, “How then will they call on him in whom they have not believed?

And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching? And how are they to preach unless they are sent? As it is written, ‘How beautiful are the feet of those who preach the good news!’” God’s Spirit calls the person who shares the gospel message, sends that person to others who have yet to hear, and empowers the message communicated and draws unbelievers to come to faith in Christ (John 6:65).

Third, the positive acceptance of the gospel message by an unbeliever is dependent upon the Holy Spirit. Both the sender and the receiver of the gospel message require God’s Spirit at work within them for the evangelistic efforts of an apologist to be effective. The Holy Spirit’s role in apologetics was clearly seen on the Day of Pentecost in Acts 2. After being empowered by the Holy Spirit, the apostle Peter defended Jesus as the Messiah, resulting in 3,000 people believing and being baptized (Acts 2:41). Throughout the book of Acts the Holy Spirit filled believers with the power to speak God’s message with boldness (Acts 4:8,31) and led them to evangelize the lost (Acts 8:29,40).

Speaking the Truth in Love

A second role in which apologetics is dependent upon the Holy Spirit is found in Ephesians 4:15: “Speaking the truth in love, we are to grow up in every way into him who is the head, into Christ.” Francis Schaeffer said, “Biblical orthodoxy without compassion is surely the ugliest thing in the world.”[2] An apologist is called to speak God’s truth with God’s love. Doing so is a sign of maturity. However, to speak in love requires the work of the Holy Spirit, because love is a fruit of the Spirit (Galatians 5:22-23).

Furthermore, God is love, and love comes from God (1 John 4:8). Thus, the person who desires to speak the truth in love must trust in God’s Spirit to effectively accomplish this aspect of sharing truth. Love also stands at the heart of the Christian message. Jesus taught that the greatest commandments are to love God completely and to love your neighbor as yourself (Matthew 22:34-40). Jesus demonstrated such love through His life and teachings. He further called His disciples to follow His example. The apostle Paul utilized this approach, calling his readers to “be imitators of me, as I am of Christ” (1 Corinthians 11:1).

There is another way in which we are dependent upon the Holy Spirit to do apologetics and to help us speak the truth in love—He gives us love for other people. It is easy to argue with someone we do not love. However, God’s love compels us to lovingly persuade those who have yet to believe the good news of Jesus. This motivation can drive us toward devoted prayer, personal holiness, committed study of accurate sources, and a diligent pursuit of opportunities to discuss and defend Christian beliefs to evangelize unbelievers and edify believers.

Moreover, our dependence upon the Holy Spirit when defending the faith also involves the uniqueness of Christian love. Other religious movements often seek to promote their beliefs as a means of gaining favor or securing their salvation by their good works. In Christianity, our love for others is based on God’s love for us. Therefore, it is unselfish, directed at others, and focused on the enrichment of others.

With God’s Spirit at work in and through the life of the apologist, this love is offered through friendship, discussion, debate, and other means to help the life of the lost person. Even in cases in which the unbeliever remains unpersuaded, the believer maintains unconditional love, knowing that the Holy Spirit must do His work to bring change into the heart of the unbeliever. Ultimately, it is He alone who illuminates the mind, confirms the truth, and changes the unbeliever’s heart (1 Corinthians 2:14-15). Thus, no one comes to faith in Christ apart from the gracious work of the Holy Spirit.

Apologetics with Gentleness and Respect

Another important aspect of apologetics is to persuade others “with gentleness and respect” (1 Peter 3:15). To be gentle and show respect requires the believer to be dependent upon the Holy Spirit. Gentleness is also a fruit of the Spirit (Galatians 5:23). Jesus served as one who was “gentle and lowly in heart” (Matthew 11:29; see also 21:5). Paul wrote with humility and gentleness when he corrected believers in Corinth (2 Corinthians 10:1).

Throughout Scripture, living with gentleness toward others stands as a clear calling for every believer. Philippians 4:5 calls believers to “let your gentleness be evident to all” (NIV). God’s chosen people are to show “gentleness and patience” (Colossians 3:12), while church leaders are to be “not violent, but gentle” and “to be gentle toward everyone” (1 Timothy 3:3; 6:11; Titus 3:2). Wives are likewise called to have a gentle spirit (1 Peter 3:4). The context of each of these passages toward believers includes a close walk with God and living by the power of His Spirit.

Respect also is an important trait for all believers, and it requires dependence upon the Holy Spirit. Believers are to respect everyone (1 Peter 2:17) and show respect to governing authorities (Romans 13:7). Wives are called to respect their husband (Ephesians 5:33), husbands are to respect their wives (1 Peter 3:7), slaves were to respect their master (Ephesians 6:5; 1 Timothy 6:1). The daily life of the believer is to win the “respect of outsiders” (1 Thessalonians 4:12 NIV). Further, church elders are to be respectable and manage their family “in a manner worthy of full respect” (1 Timothy 3:4 NIV). Likewise, deacons and their families are to be “worthy of respect” (1 Timothy 3:8,11 NIV). In apologetics, showing respect for unbelievers and their beliefs and backgrounds can often remove barriers to sharing the gospel.

For example, rather than disrespecting a Buddhist’s belief in reincarnation, a respectful apologist can instead discuss what evidence exists for reincarnation. He or she might also help the adherent better understand the historical origin of this belief. A conversation may then lead toward the biblical discussion of eternal life and the need for faith in Jesus Christ to receive it. The goal, in this context, would be to help the person understand there is one life and then judgment (Hebrews 9:27), while respectfully appealing to the opportunity to obtain through Jesus an eternal life better than reincarnation (Ephesians 2:8-9).

Addressing False Teachings

In Titus 1:9, the apostle Paul instructed that a church elder “must hold firmly to the trustworthy message as it has been taught, so that he can encourage others by sound doctrine and refute those who oppose it.” Jude verse 3 adds, “I was very eager to write to you about the salvation we share, I felt compelled to write and urge you to contend for the faith that was once for all entrusted to God’s holy people.” The Christian faith includes both a positive communication of the gospel and a defense against inaccurate teachings. Jude felt “compelled” by the Holy Spirit to address certain false teachings, leaving an example for believers today.

In Titus 1:9, the New Testament Greek word translated “sound” (hugiainō)—in reference to sound doctrine—can also be translated “healthy.” Certain teachings are unhealthy and inaccurate, requiring a response from the apologist. Those gifted in teaching by God’s Spirit can often most effectively address such errors. However, all believers are called to “be steadfast” and “stand firm” in the faith (1 Corinthians 15:58; 16:13).

Addressing false teachings involves both the intellect and the heart. The believer is called to present accurate beliefs or ideas regarding God, yet a spiritual side also exists. Paul addressed this in Ephesians 6:10-20, noting the need to wear “the whole armor of God” (verse 13).

Part of this spiritual armor includes “the sword of the Spirit” (verse 17). Paul refers to this spiritual sword as the Word of God. In this context, a direct association is made between the Holy Spirit and Scripture working together to respond to false teachings. Powerful examples of this method are found in the New Testament. Jesus responded to the three temptations of Satan in the wilderness by appealing to Scripture (Matthew 4:1-11; Luke 4:1-13). Matthew’s Gospel frequently cited Old Testament passages in support of its accounts, a method followed to various degrees by the other Gospel writers. The apostle Paul also frequently cited from the Old Testament to support his teachings, as did James, Jude, and the author of Hebrews. In fact, a compelling case can be made that every New Testament author strongly utilized the Old Testament in their writings.

A further aspect of addressing false teachings through the Holy Spirit is prayer. In Colossians 4:3-4, Paul wrote, “At the same time, pray also for us, that God may open to us a door for the word, to declare the mystery of Christ, on account of which I am in prison—that I may make it clear, which is how I ought to speak.” He clearly relied on the Holy Spirit’s power, his own prayers, and the prayers of other believers to strengthen his apologetics arguments. This was true both when he communicated Christ to unbelievers and he addressed false teachings. James 1:5-8 also addresses the need for believers to pray for wisdom when it is lacking, trusting the Lord to provide it.

Prayer appeals for the spiritual power necessary for effective apologetics in all areas in which wisdom is needed, both in presenting and defending the gospel message.

In John 14:16-17, Jesus told His followers, “I will ask the Father, and he will give you another Helper, to be with you forever, even the Spirit of truth.” Followers of Christ receive the Holy Spirit as an ongoing helper and advocate. He is the Spirit of truth that empowers the life and communications of the apologist. Reasoning alone saves no one apart from the work of the Holy Spirit. He alone prompts people to believe in God’s saving truth, and He alone enlightens the unbeliever’s mind to understand the evidence of His truth.
