1 John 3:16-24 NRSV
We know love by this, that he laid down his life for us—and we ought to lay down our lives for one another. How does God's love abide in anyone who has the world's goods and sees a brother or sister in need and yet refuses help?
Little children, let us love, not in word or speech, but in truth and action. And by this we will know that we are from the truth and will reassure our hearts before him whenever our hearts condemn us; for God is greater than our hearts, and he knows everything. Beloved, if our hearts do not condemn us, we have boldness before God; and we receive from him whatever we ask, because we obey his commandments and do what pleases him.
And this is his commandment, that we should believe in the name of his Son Jesus Christ and love one another, just as he has commanded us. All who obey his commandments abide in him, and he abides in them. And by this we know that he abides in us, by the Spirit that he has given us.
