"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."
"And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight. And this is his commandment, that we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment. And he that keepeth is commandments dwelleth in him and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us."
"For this is the love of God, that we keep his commandments: and his commandments are not grievous."
"And this is love, that we walk after his commandments, this is the commandment, that, as ye have heard from the beginning, ye should walk in it." - I John 2: 3-5, 3: 22-24, 5: 3; 2 John 6
