What does 'substitute' mean in the Bible?

Answer 1

You were acutually asking "Substitute", not "Subsitute, I guess. There are two aspects to answer this question. 1. Christ died for us or on behalf of us on the cross. We are sinners and doomed to be judged by God on an appointed day(Heb 9:27). But Christ came in the flesh(John 1:14) and died on our behalf. He is the Lamb of God(John 1:29). In this regard Christ is our Substitute. 2. Christ resurrected and entered in all those who believe into Him, thus lives in them, live through them, and lived out by them. That's why Apostle Paul can proclaim "　I am crucified with Christ; and it is no longer I who live, but it is Christ who lives in me. ; and the life which I now live in the flesh I live in faith, the faith in the Son of God, who loved me and gave Himself up for me." (Gal 2:20)Pauldid not live by his naturallife, rather he lived a life which is a mingling ofGod's life and hislife that has been crucified, resurrected and upliftedwith Christ.This life is a grafted life(Rom 11:24). Therefore for anormal Christian his natural life is substituted by this grafted life.
