All of your days have already been written in God's book. When you go through a disappointment, don't stop on that page. Stay the course. Keep believing. You may be tired, discouraged and frustrated, but don't give up on your future. Our God is faithful.
TRUST IN GOD. I know every now & then, god will even give us the things that we want! this doesn't mean material things, of course. But the bible says delight yourself in HIM, and he WILL GIVE YOU the desires of your heart!
