By this we know that we love the children of God, when we love God and keep His commandments.
For this is the love of God, that we keep His commandments. And His commandments are not burdensome.
For whatever is born of God overcomes the world. And this is the victory that has overcome the world--our faith.
References for 1 John 5:4
Who is he who overcomes the world, but he who believes that Jesus is the Son of God?
