What God Does for His People (vv. 12-13). We have read the whole story, so we know that God did maintain David’s cause, defeat his enemies, and keep His promise to put him on the throne of Israel. David would establish a dynasty that would eventually bring the Savior into the world. He would write nearly half of the psalms, he would expand and defend the borders of the kingdom, and he would make the preparations necessary for the building of the temple. What a great man he was because he trusted in the Lord! David was grateful to God for His intervention, and he determined to live to glorify the God of Israel. David wrote, “The Lord will accomplish what concerns me” (138:8 nasb), and God honored His faith. For God’s devoted people, the best is yet to come. Yield to Him and He will accomplish what He has planned for you, and you will be satisfied.
