"The eye never has enough of seeing, nor the ear its fill of hearing." Ecclesiastes 1:8
Human nature is never satisfied. God gives us gifts but we want more, we're always waiting for the next good thing. If you are dissatisfied with life, ask yourself why. You'll never be satisfied if you are filling your life with things that don't last. Try filling your life with God, He will satisfy until you grow discontent then He'll give you more. He is inexhaustible in His riches!
