We cannot put too great emphasis upon the duty of giving happiness and cheer to others. But it is no less a duty that we should be happy and cheerful ourselves. All our efforts to lighten another's load will be limited unless they spring from a source of joy within.

When you yield to discouragement, by that act you are saying that you do not believe God's Word, and you have listened to Satan's lying vanities and put yourself out of the reach of God's mercy until you confess and repent from the heart.
