If you truly love the Lord you follow all of his commandments.
His commandments are not grevious, you cant just follow one commandment , and if you are truly loving your god and have real faiith you follow all of his commandments.
You go to church , you take communiuon and you repent for your sins.
As Paul himself said. he himself could be cast away.
Read and study Matthew, Mark, Luke, John and revelations and see all the If's and warnings for the believers who claim they Love and have faith in him.
Christ came to save all his believers, he did not judge us yet on our walk with him. He will come to judge the living and the dead.
