It has nothing to do with showing a lot of effort. The whole point is to love God sincerely; to love God with a deep, profound love. If you love God, you are strong. I mean if you love God a lot, you would definitely be victorious. Look I am not saying that “if you believe in God”, I am saying “if you love God”. Actually to feel love, you have to believe in Him. - Harun Yahya
