In his letter to Titus, Paul provided a brief summary of the purpose of God’s plan of salvation. Paul said:
God’s free gift of being saved is being given to everyone. We are taught to have nothing to do with that which is against God. We are to have nothing to do with the desires of this world. We are to be wise and to be right with God. We are to live God-like lives in this world. We are to be looking for the great hope and the coming of our great God and the One Who saves, Christ Jesus. He gave Himself for us. He did this by buying us with His blood and making us free from all sin. He gave Himself so His people could be clean and want to do good. (Titus 2:11-14, NLV)
In a nutshell, Paul stated that the purpose of God’s plan of salvation was to change people’s lives. Paul said we are to live “God-like lives” (Titus 2:12, NLV). This phrase would have no meaning if it weren’t for the example that Jesus gave us when he was alive on Earth. We can know for sure what we are supposed to do as Christians because of the life of Jesus.
Paul said that Jesus “gave Himself so His people could be clean and want to do good” (Titus 2:14, NLV). In the King James version it says that Jesus wanted to “purify unto himself a peculiar people.” The Greek word translated peculiar, periousios (per-ee-oo’-see-os) has to do with “being beyond usual, i.e. special (one’s own possession)” (G4041). What actually happens when we become Christians is we take on Jesus’ characteristics. It’s not something that we have to try to do or pray for it to happen. It is a natural result of being born again. We become children of God (God-like).
The change that happens when we accept Jesus as our savior is both instantaneous and occurs over the course of our lifetimes. Paul said, “Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new (2 Corinthians 5:17). Paul described this instantaneous change as reconciliation (Colossians 1:20-21) and said that it resulted in peace with God. The change that occurs over the course of our lifetimes and results in our transformation into the image of Christ is referred to by Paul as sanctification. This is what makes us want to do good things or as it says in the King James Version, “zealous of good works” (Titus 2:14).
To be zealous for something means that it heats you up or gets you emotionally charged. Another way of saying it would be you’re passionate about it. The unusual or special thing about Christians is that they are passionate about helping people, doing good things for others. In a nutshell, that was the purpose behind God’s plan of salvation and the reason why Jesus was willing to die on the cross.
