Do you not know? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom. He gives strength to the weary and increases the power of the weak. —Isaiah 40:28-29.
God is eternal. He has unlimited power. His supply of strength is limitless. He blesses and shares his grace without growing tired. Most importantly, he longs to share his power and grace with you and me daily.
