Hi Leon~ These expressions come from the world of playing cards, as in a poker game. The dealer gives out the cards to everyone who is playing one at a time going around from person to person. When everyone has the proper number of cards the game starts. And depending on which cards you were dealt, you may have a winning or losing hand. "Hand" is what your assortment of cards is called because you hold them in your hand.

If your cards have higher value than those of others, you have a winning hand. If they are of a lower value than others, you have to figure out how best to play a losing hand. I don't think this means God is recommending everyone start playing poker.
