We don't ask God BIG things; not because we are shy but we doubt God's ability. Remember, the whole mankind put together can't  bankrupt God, even in our wildest imaginations. God is God, man is man, dust is dust. God always counsel's us to believe but never even once suggested us to reason Him. So, just trust God.
