Dealing with discouragement:
You first need to acknowledge what the problem is. We should not live in denial as Christians. Having faith does not mean that you live in denial. It means you acknowledge where you are and receive faith through God's word to know that that situation can go in the mighty name of Jesus Christ.
Every time discouragement knocks at your door, remember; remember where the Lord brought you from, how merciful He has been to you, and the good things He has done not only for you but also for other people.
