With your use of the verse from Thessalonians, I certainly hope that you are not calling the death, burial and resurrection of my Saviour a lie.
No, I am not. I am calling the religion that says we should not follow Christ in deed and thought a lie. Jesus kept the Law. We are to keep the Ten Commandments as He did. He is our example. The religion of the world says faith alone saves. But faith without works is dead. DEAD. Will God allow sin in heaven? The answer is NO. We are to obey his Commandments or we are in rebellion.
