When you're travelling on the road of life and the way becomes conjested--BELIEVE! When God has promised something, but it seems that He has failed--that's right, BELIEVE! Because all throughout life you will be tempted to doubt, but when you do, you need to make the decision to believe anyway.
"I believe in the sun, even when it is not shining. I believe in love, even when I feel it not. I believe in God, even when He is silent."
