(Isaiah 40:29*). * Isaiah 55:11 – So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. * Isaiah 40:29 – He giveth power to the faint; and to them that have no might he increaseth strength.
