1 John 5: 1 - 4
1 Every one who believes that Jesus is the Christ is a child of God, and every one who loves the parent loves the child.
2 By this we know that we love the children of God, when we love God and obey his commandments.
3 For this is the love of God, that we keep his commandments. And his commandments are not burdensome.
4 For whatever is born of God overcomes the world; and this is the victory that overcomes the world, our faith.
