Hast thou not known? hast thou not heard, that the everlasting God, the LORD, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding. He giveth power to the faint; and to them that have no might he increaseth strength. (Isaiah 40:28-29)1/ The LORD, the Creator .2/ His energy and his wisdom .3/ What he gives and to whom .4/ A warning and two exhortations .
