“O Lord, my heart is not lifted up.” David was one of the great kings of Israel. He also wrote many psalms and received mighty revelations from God that have now been fulfilled in the death and resurrection of the Messiah. The Lord chose David above all his fellow Israelites to be the beginning of a great dynasty that would last forever. Yet this chosen man did not puff himself up in arrogance. He was humble before the Almighty.David did not allow his heart to be unsettled about matters that were “too great and too marvelous” for him. He deliberately rested upon the Lord. He “calmed and quieted” his own soul like an obedient toddler who was secure in the embrace of his mother. His soul found peace in God though there were many weighty matters swirling all around him.All of David’s subjects needed to consider the king’s testimony regarding his quiet heart. “O Israel, hope in the Lord from this time forth and forevermore.”Many centuries after David’s life on earth was over, the king’s greatest descendant was born. At one point during His ministry when His companions were concerned with the wind and waves threatening their safety, Jesus was able to sleep in peace. The disciples were sure that they were perishing. They were consumed by their fears. He said to them, “Where is your faith?” (Luke 8:25)Our faith is in Jesus today. We hope in the Son of David who died for our sins. He is able to calm the winds and the waves. He will accomplish all of His perfect purposes.
