Forgive me if I am wrong but, are you saying that Christians do not ever sin?? That they live sinless lives, just like Jesus?? Do you not know that we all have a parasite called "sin" living in us? When Paul wrote, “We died to sin; how can we live in it any longer?” he wasn't referring to the activity of committing sins, he was talking about living under the dominion of sin. The word live means to continue in or abide in.
1st John 5:16 “If anyone sees his brother” — a Christian — “committing a sin not leading to death, he shall ask, and God will give him life.” <---- Tells me that Christians can indeed sin.
1 John 1:8–10. “If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say we have not sinned, we make him a liar, and his word is not in us.”
