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.
We have this confidence when we keep His commandments and we do those things that are pleasing in His sight. Then we have power in prayer, because our prayers are not directed towards our self-interest and our own self-aggrandizement, but our prayers are on the things of His kingdom and things for His glory and things whereby others may prosper and be blessed.
