Let us give thanks to God continually. For, it is outrageous that when we enjoy His benefaction to us in deed every single day, we do not acknowledge the favor with so much as a word; and this, when the acknowledgment confers great benefit on us. He does not need anything of ours, but we stand in need of all things from Him. In point of fact, thanksgiving adds nothing to Him, but it brings us closer to Him.
–Saint John Chrysostom (347-407
