Joshua 1:18

Whosoever he be that doth rebel against thy commandment and will not hearken unto thy words in all that thou commandest him, he shall be put to death; only be strong and of a good courage, a call with which the two and one half tribes intended to give Joshua the assurance which he needed at the beginning of his difficult work that he could depend upon the people whom the Lord had given into his charge. In the New Covenant it is also the will of God that His children help one another in the severe spiritual battles which they must fight, giving one another all possible encouragement at all times. They are assured, even now, of eventual entrance into their rest. "He who follows the Word of God acts wisely and happily, but he who follows his own reason acts unwisely and to no profit. " (Luther.)
