"I, the Vine, have taken you to be My branches.... I have surrendered Myself as God absolutely to you; I became Man and died for you that I might be entirely yours. Come and surrender yourselves entirely to be Mine."

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.
