There are a number of psalms, beginning with this one, that are expressions of the heart's cries and confidence of the godly. These are not just a list of requests that so often characterize the prayers of many of God’s people, but these are the expressions of faith in God that are from the hearts of those who truly love the Lord. They want their Lord to know the sincerity of their own souls rather than just the perceived needs they have. Such people have a spiritual instinct that leads them to the throne of grace.
That instinct comes from listening to what God says in His word and learning from what they hear to the extent that it becomes their life practice. When we come to the throne of grace, we “obtain mercy and find grace to help in time of need.” Our safety and security are real to us because we look at things from the divine perspective. Answered prayers keep us coming back again and again to the throne because we have experienced divine grace. Like the psalmist, we want the sense of God’s presence and protection. We find the mercy we need when we feel overpowered at the throne of grace. We see the safety that lifts us above what is expected to where our sigh of relief is from deep within. The security, strength, and confidence we have not naturally found there come from our gracious Father's hands.
The Rock is there, but it is “higher than I,” so we need help from the Lord to climb to that place of calm assurance and quiet rest. Our Lord Jesus Christ is not just a mere man. He is the “Rock that is higher than I [am].” He is a strong tower, a mighty fortress, and a place of safety from enemies that threaten the soul. Only God can bring us to this Rock. He never fails as a place of refuge. His blessings to us in the past give us hope for the present and future. The covering of His “wings” is a comforting shelter when there is anxiety and uncertainty.
The second part of this psalm is a prayer for blessing. Likely, it is David’s prayer for himself, although in this place, he makes his prayer in the third person. He knows God has heard, “Thou hast heard my vows,” so now he is committed to keeping those promises. We find it easy to ask God for help and for things we think we need. The other side of the matter is, what do we promise to give Him? What do we promise to do for Him? These vows may not be obligatory, but they are evidence of appreciation and sincerity on our part.
In David’s second prayer in this psalm, he asks for God to prolong “the king’s life.” He asks for the king’s reign to be extended and for God to give blessings of mercy and truth. We know God has all-surpassing strength, which is available to us from Him. Our spiritual “heritage” is significant, varied, and just what we need. The people of God are our people. The word of God is the food required for our souls. As children in God’s family, we have “all things in Christ.” We are kept safe by God’s power. The “house of God” is where we belong and find our recourse when pressured to live in this world.
Like the psalmist, our confidence in God makes us determined to pay our daily vows of thanksgiving. That is one way we express and affirm our trust. The vow of praise is personal, and public praise is in order when we share the blessings God has bestowed on us with our spiritual family. The closer we are to God, the more we realize how high and lofty He is and how great our need is for His mercy. Praise is a choice to be made daily when our hearts and minds are above distractions. That exercise of the heart leads us to where our confidence is truly in God. This psalm begins in urgency and ends in serenity. That is the experience of those who have actually cast their care upon the Lord, knowing that “He will sustain thee.”
