How do you "Convert" somebody to Christianity? A highly debated topic I know. There are hundreds of answers for this, but I would personally like to know what the Bible says about this.

If somebody was interested in being saved, what is my responsibility as a disciple of Christ to do?
I don't wish to sound flippant but you don't convert anyone. God does. Having said that, our responsibility is:


To explain the hope we have, and be ready to do this, with gentleness and respect. 1 Peter 3v15


Then we can explain the theology, if people want to know. It comes down to this:


God is perfect (Deuteronomy 32:4, Matthew 5:48). That's His standard and His requirement to be with Him forever.
No human however is perfect (Romans 3:23).
Jesus is God become man (John 1:14). Therefore, He is a (and the only) perfect human.
Jesus offers to swap His righteousness for our sins (2 Corinthians 5:21). This is possible because He sacrificed Himself for us on the cross (Philippians 2:8).
Therefore we can immediately, on turning to Jesus, been declared perfect (forgiven) in the eyes of God (Acts 10:43).


As one of my friends once said, summarising the whole Gospel in seven words, "We don't reach Him, He reaches us."
