This is a very familiar passage in a very famous letter:
"Little children, let us not love in word or talk but in deed and in truth. By this we shall know that we are of the truth and reassure our heart before him; for whenever our heart condemns us, God is greater than our heart, and he knows everything. Beloved, if our heart does not condemn us, we have confidence before God; and whatever we ask we receive from him, because we keep his commandments and do what pleases him. And this is his commandment, that we believe in the name of his Son Jesus Christ and love one another, just as he has commanded us."
What does the phrase in italics mean, in light of the surrounding context? It is not immediately obvious, and I have a feeling that many Christians assume a meaning that is not likely. What do you think it means?
