Because Christ became like one of us, we now have the opportunity to become like Him. Christ was manifested in the flesh, and now His life can be manifested in our flesh.
Jesus Himself has called us to be a disciple, His follower. This is the greatest calling that a human can have.
The scriptures are not ambiguous concerning victory over sin. A victorious life is fully possible, and living in sin is completely unnecessary. No one needs to be a slave to sin.
