Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the Father loves whoever has been born of him.
By Obeying His Commandments,
1 John 5:2 ESV
By this we know that we love the children of God, when we love God and obey his commandments.
By Overcoming the World,
1 John 5:4–5 ESV
For everyone who has been born of God overcomes the world. And this is the victory that has overcome the world—our faith. Who is it that overcomes the world except the one who believes that Jesus is the Son of God?
