If what you say is true, then there would have been no need for the apostle John to tell us in plain words in 1 John:
8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
10 If we say that we have not sinned, we make him a liar, and his word is not in us.
This is addressed to Christians, since only Christians can have fellowship with God, and the context is fellowship with God. So it is a very serious matter to invent your own theology and imagine that you are sinlessly perfect.
