1 John 5:2-5 NLT

2 We know we love God's children if we love God and obey his commandments.
3 Loving God means keeping his commandments, and really, that isn't difficult.
4 For every child of God defeats this evil world by trusting Christ to give the victory.
5 And the ones who win this battle against the world are the ones who believe that Jesus is the Son of God.
