Didnt say that Pony, but its really not a sacrifice to give up something the law says you shouldnt be doing in the first place. The Bible does say obey the laws of the land, and that is a law of the land.

Besides, when this kid says to give up alcohol, hes giving up not getting trashed for 40 days. Its not like hes giving up his glass of wine with dinner at night. Being that the Bible also says you shouldnt endulge in drunkeness, in this case it makes it even less of a sacrifice.
