Philemon 1:20

For if I make you sorry, who is he then that maketh me glad, but the same which is made sorry by me?

Great is my boldness of speech toward you, great is my glorying of you: I am filled with comfort, I am exceeding joyful in all our tribulation. For, when we were come into Macedonia, our flesh had no rest, but we were troubled on every side; without were fightings, within were fears. Nevertheless God, that comforteth those that are cast down, comforted us by the coming of Titus; And not by his coming only, but by the consolation wherewith he was comforted in you, when he told us your earnest desire, your mourning, your fervent mind toward me; so that I rejoiced the more.

For what is our hope, or joy, or crown of rejoicing? Are not even ye in the presence of our Lord Jesus Christ at his coming?

Therefore, brethren, we were comforted over you in all our affliction and distress by your faith: For now we live, if ye stand fast in the Lord. For what thanks can we render to God again for you, for all the joy wherewith we joy for your sakes before our God;

Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that is unprofitable for you.

I have no greater joy than to hear that my children walk in truth.
