“O God, You have taught me from my youth, And I still declare Your wondrous deeds. And even when I am old and gray, O God, do not forsake me, Until I declare Your strength to this generation, Your power to all who are to come.” Ps 71:17‭-‬18

The name of this Psalm, in most translations clearly notated before verse one is entitled, “The prayer of an old man for deliverence”. This was the last Psalm that David ever wrote, probably written very near the end of his life and reign, and its very reflective in nature.
David was 70 years old when he died. He had ruled Israel or a portion of Israel as King since he was 30, a total of 40 years! In that time David had seen more than his share of close calls and calamity. He’d been chased, betrayed, had spears thrown at him, had faced ambush, battle and death numerous times, but in all his years from shepherd boy to king, he had never lost focus of Who was his Defender, Sustainer, Supplier Healer and Strength-he believed in God! He believed in His power, His strength, His provision, His proction and His sovereignty! He had worshipped God all his life, and now, as an old man, his expectation was that he would continue proclaiming God’s goodness to the world around him.

God’s goodness and David’s knowledge of Him, sustained David for life! What sustains you? Think about it!
