In John 4:5–42, we have two examples of evangelism—one in Jesus and the other in the Samaritan woman. She invited others to meet Jesus, they came, and many believed in Him. However, what follows below are five practical points for evangelism from looking at Jesus Himself in His example of giving the truth to the Samaritan woman.
First, speak to someone no matter who they are.
Jesus spoke to a woman who was a Samaritan. Her gender and ethnicity were two characteristics that typically would have resulted in prejudice and a non-conversation between a Jew and a Samaritan. She herself was surprised that Jesus spoke to her in light of these characteristics (John 4:9), and the disciples were surprised at the conversation as well (John 4:27). But Jesus looked past these matters and saw her for what she was—a sinner in need of salvation in Him.
Second, use something in your conversation to transition to the gospel.
The woman spoke of water. Jesus turned the conversation to living water (4:10). She did not understand right away, but He persisted in steering the conversation to dealing with her sin and what she thought of Himself as the Messiah. While we don’t want to rudely force an unwanted conversation onto someone, it may be that gently turning the conversation to the gospel is what God uses to save others through us.
Third, point out man’s alienation from God.
The woman could not drink this life-giving water and turn to God unless she also turned from her sin—a life of living with someone other than a spouse and that after having previously lived with five husbands (John 4:16–18). Jesus answered her request for living water in John 4:15 by focusing on her sin in John 4:16–18. No one finds salvation in Christ without repentance for his sins.
Fourth, answer any objections.
The woman tried to object that her heritage had its own religion at their mountain, and the Jews had their own as well in Jerusalem (John 4:20). However, Jesus cared nothing for geography. All men were to now worship the Father, wherever they may be (John 4:21–24). He even flatly denied any validity to her religion: “You worship what you do not now” (John 4:22 ESV). Answering objections may mean eventually stating that the reasons for an objection are simply wrong.
Fifth, point the unbeliever to Christ.
Jesus concluded by pointing the woman to Himself as the Messiah. She believed, brought others to Him, and they believed in Him as well (John 4:25–26). Evangelism is simply not evangelism if it does not point the sinner to Christ. Salvation is found in Him alone.
