Good Deed Quotes (page 4)
As water cannot rise higher than its source, so the moral quality in an act can never be higher than the motive that inspires it. For this reason no act that arises from an evil motive can be good, even though some good may appear to come out of it. Every deed done out of anger or spite, for instance, will be found at last to have been done for the enemy and against the kingdom of God.
