When we say spiritual, we are dealing with spiritual substance , spiritual tangibility. Gods interpretation of our prayers and sacrifices , for example is spiritual even the prophets could see it that way , in Hosea 14:2, the Bible says TAKE WITH YOU WORDS , AND TURN TO THE LORD: SAY UNTO HIM, TAKE AWAY ALL INIQUITY , AND RECEIVE US GRACIOUSLY : SO WILL WE RENDER THE CALVES OF OUR LIPS.
