Brothers and sisters in Christ, let us keep in our hearts a love for the truth and the crucified way, lest we be led astray by any of the deceivers around us.... Those who get grounded and settled in the truth will not be blown about by different winds of doctrine.

To be the voice of one crying in the wilderness in this way... is to abandon all human planning and direction.... It is to forsake that peculiar fleshly confidence that comes from human reasoning and second-guessing God.

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.
