"And hereby we do know that we know him,if we keep his commandments.
He that saith,I know him,and keepeth not his commandments,is a liar,and the truth is not in him.
But whoso keepeth his word,in him verily is the love of God perfected:hereby know we that we are in him.
He that saith he abideth in him ought himself also so to walk,even as he walked. "
1 John 2:3-6
