Here is an interesting article by Mike Ratliff:
Don’t answer a fool according to his folly, Lest you also be like him. Answer a fool according to his folly, Lest he be wise in his own eyes. (Proverbs 26:4-5 WEB)
Evangelism that is biblical is not numbers or results based as if it is a process we can control through methodology. The seeker-sensitive form of evangelism, on the other hand, is totally numbers or results based, and, therefore, uses methodologies to boost perceived effectiveness by increased numbers of “decisions for Christ.” The seeker-sensitive form of evangelism assumes that God is helpless to save anyone outside of their efforts. It ignores passages such as John 3:5-8 and Ephesians 2:1-10.
Jesus answered, “Most assuredly I tell you, unless one is born of water and spirit, he can’t enter into the Kingdom of God!That which is born of the flesh is flesh. That which is born of the Spirit is spirit. Don’t marvel that I said to you, ‘You must be born anew.’The wind blows where it wants to, and you hear its sound, but don’t know where it comes from and where it is going. So is everyone who is born of the Spirit.” (John 3:5-8 WEB)
In this passage, Jesus tells us that people are Born Again by the Spirit and His work in this is like the wind which no one can control or perceive.
