Isn't it better to live the world believing in God and die finding none, than to live the world as a non-believer only to find (after we die) that there really is GOD. (It'll be too late then.)But for sure God exists. Otherwise, Who gives us life? Who creates this world?
Don't wait until you have extra in order to give something to someone, just share whatever you have eventhough it might be little. It is the act of kindness that the counts most and not so much the amount you give.
