Question: "What is the biblical method of evangelism?"
Answer: When trying to decide how to share Christ with someone, the starting point should be the same as that of John the Baptist and Jesus Himself. Matthew 3:2 tells us that John began his ministry with the words “Repent, for the kingdom of heaven is near.” Repentance refers to a “change of mind,” which implies sorrow for past offences (2 Corinthians 7:10), a deep sense of the evil of sin as committed against God (Psalm 51:4), and a conscious decision to turn from sin to God. The first words Jesus spoke when He began His public ministry were identical to John’s (Matthew 4:17).
Biblical evangelism – The good news and the bad news
The word "gospel" means "good news." While many well-meaning Christians begin their evangelistic efforts with the good news of God’s love for mankind, that message is lost on unbelievers who must first come to grips with the extent of the bad news. First, man is separated from a holy, righteous God by sin. Second, God hates sin and is “angry with the wicked every day” (Psalm 7:11). Third, death and judgment are inevitable (Hebrews 9:27). Fourth, man is wholly incapable of doing anything about the situation. Until the full extent of this bad news is presented, the good news cannot be effectively communicated.
Biblical evangelism – The holiness of God
What is missing from much modern evangelism is the holiness of God. In Isaiah’s vision of heaven, God’s holiness is being extolled by the seraphim around the throne. Of all the attributes of God they could have praised, it was His holiness—not His love—of which they sang. “And they were calling to one another: ‘Holy, holy, holy is the LORD Almighty; the whole earth is full of his glory’" (Isaiah 6:3). When we understand just how holy God is, we can begin to understand His hatred of sin and His righteous wrath against sinners. Zechariah 8:16-17 and Proverbs 6:16-19 outline the sins God hates—pride, lying, murder, false witness, those who stir up trouble, and those with evil in their hearts. We cringe at the idea of God actually hating, because we are more comfortable with Him as a God of love, which He certainly is. But His hatred is real and it burns against evil (Isaiah 5:25; Hosea 8:5; Zechariah 10:3).
The unsaved person stands in mortal peril of the wrath of holy God, as Hebrews 10:31 reminds us: “It is a dreadful thing to fall into the hands of the living God.” An unbeliever is separated from God by his sin, which God hates, and there is nothing he can do about it. His nature is corrupt and fallen and he is “dead in trespasses and sins” (Ephesians 2:1) with no hope of redeeming himself. He cannot save himself, in spite of good intentions or good works (Romans 3:20). Every good work that man thinks he can do is as “filthy rags” in God’s sight (Isaiah 64:6). No amount of good living will make us acceptable in God’s eyes because the standard is holiness, without which no one will see God (Hebrews 12:14).
Biblical evangelism – Salvation through Jesus Christ
But now comes the good news. What man could not do to save himself, God accomplished on the cross. Jesus exchanged His righteous, holy nature for our sinful nature so that we can stand before God completely clean and pure, new creations with the old sin nature gone forever (2 Corinthians 5:17-21). God provided the perfect sacrifice for our sin, not because we deserved it or earned it, but because of His love and grace and mercy (Ephesians 2:8-9). Only those whose natures have been changed can escape the wrath of God and live in the light of His love and mercy. If we believe these things and commit our lives to following Christ by faith, we will live eternally with Him in the bliss and glory of heaven. This is good news indeed.
Biblical evangelism begins with prayer for the guidance of the Holy Spirit in witnessing, open doors of opportunity, and a clear understanding of the bad news of sin and wrath and the good news of love, grace, mercy and faith.
