Disappointment is inevitable. But to become discouraged, there's a choice I make. God would never discourage me. He would always point me to himself to trust him. Therefore, my discouragement is from Satan. As you go through the emotions that we have, hostility is not from God, bitterness, unforgiveness, all of these are attacks from Satan.
There's a lot of mediocrity being celebrated, and a lot of wonderful stuff being ignored or discouraged.
Edison failed 10,000 times before he made the electric light. Do not be discouraged if you fail a few times.
Young people can get very discouraged and get hooked on drugs or on alcohol because of problems they perceive as insurmountable. It is important that they realize a mistake need not ruin their future, but they must also know that not everything in life is a bed of roses.
It is possible to become discouraged about the injustice we see everywhere. But God did not promise us that the world would be humane and just. He gives us the gift of life and allows us to choose the way we will use our limited time on earth. It is an awesome opportunity.
