Strive for excellence, not perfection, because we don't live in a perfect world.
You are not free until you have no need to impress anybody.
Seek His face and not His hand.
God is bigger than every issue you will ever have to face, and you can do whatever you need to do through Christ who strengthens you.
It`s important to have a relationship with God. He's the only one that can get down inside of you and heal what needs to be healed inside.
Peter was the only one who walked on water besides Jesus, but he was also the only one who got out of the boat. Until you make a decision to believe, and then act on it, nothing will happen.
