1 John 5:2-3
1 John 5:2-3 AMP
By this we know [without any doubt] that we love the children of God: [expressing that love] when we love God and obey His commandments. For the [true] love of God is this: that we habitually keep His commandments and remain focused on His precepts. And His commandments and His precepts are not difficult [to obey].
