“By this we know that we love the children of God, when we love God, and keep his commandments.”
King James Version (KJV)
5:2 Hereby we know - This is a plain proof. That we love the children of God - As his children.
1Jo 5:2 By this we know that we love the children of God. But all born of God must love God's children. The proof that we have this love is that we love God, and keep his commandments. We so love God as to obey his commandments, one of which is to love our neighbor as ourselves (Le 19:18 Mt 19:19 22:39 Mr 12:31 Ro 13:9 Ga 5:14 Jas 2:8).
