Behold, how great a love the Father has bestowed on us, that we should be called children of God! For this cause the world doesn't know us, because it didn't know him.

 3:19-24a By this we know that we are of the truth, and by this we will reassure our heart before him, when our heart condemns us in anything, for God is greater than our hearts and knows all things. Beloved, if our heart does not condemn us, we can come confidently to God and receive from him whatever we ask, because we keep his commandments and do the things which are well pleasing to him. And this is his commandment, that we should believe in the name of his Son Jesus Christ and that we should love one another, even as he gave us his commandment. And he who keeps his commandment abides in him and he in him.
