|If what you say is true than nobody is saved on this earth because everybody sins.
Romans 7:14 'For we know that the law is spiritual, but I am carnal, sold under sin.' Paul here was referring to his flesh. Later on he says. 7.20 'Now if I do what I will not to do, it is no longer I who do it, but sin dwells in me'.
1 John 2:1 'My little children, these things i write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous' If no christian ever sinned why would we need an Advocate?
1 John 1:8 'If we say that we have no sin, we deceive ourselves and the truth is not in us'.
We are saved from the power of sin that is true but christians still have their flesh to deal with and until either we die or the Lord comes we will still struggle with our own flesh and we will still sin. Jesus died for all our sins, past, present and future. He had to we weren't even born when he died.
