Son of God, who loved me and gave Himself for me

Galatians 2:20
I have been crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me

This passage shows what being a Christian is supposed to be. Usually people introduce others to Christianity with salvation, which is true and essential. Once we accepted Yshua as Massiach and our Lord, then we are crucified with Him. Paul explains this crucifixion of self as being that we need to live our lives for Him. In other words, it is about doing His will, not our own will based on our plans and desires.
