Keep your servant also from willful sins; may they not rule over me. Then I will be blameless, innocent of great transgression. May these words of my mouth and this meditation of my heart be pleasing in your sight, Lord, my Rock and my Redeemer (NIV).
We conclude this great psalm about God’s revelation. Its closing words speak joyfully about his confidence in God and the grace that is freely received from him. God’s words are intended to lead us to his joy, but that is only received as we trust in him, as he has revealed himself to us.
“Then will I be blameless, innocent of great transgression.” As David prays for help against sin, he uses the argument that such help will enable him to live for God as he should. This is the blameless character of which he speaks. He would be blameless in regard to willful or defiant sin. Every saint should make this his/her aim, as also the apostle Paul tried to live. Because of this, I always try to maintain a clear conscience before God and all people (Acts 24:16 NLT).
“May the words of my mouth and the meditation of my heart…” David concludes this psalm with what has become a very well-known prayer. Notice that he asks for God’s help with both his outer man (“my mouth”) and his inner man (“my heart”). As Jesus taught, the mouth speaks what comes out of the heart. You brood of vipers, how can you who are evil say anything good? For the mouth speaks what the heart is full of. A good man brings good things out of the good stored up in him, and an evil man brings evil things out of the evil stored up in him (Matthew 12:34-35 NIV). What David prayed showed his concern for the purity of the whole person, body and soul. We might perhaps say the right thing, but if the heart is not producing those words, we are being hypocritical.
David recognized that his heart would meditate or ponder on things that his mouth might not necessarily say, yet he wanted to be pure in heart also, for he knew that God knew what he was thinking in his heart (cf. Psalm 139:1-6). Idolatry of the heart is as evil as outward performance (Ezekiel 14:3-4). David wants God alone to be worshipped by him.
David was focused on the Lord. He desired that his words and thoughts would be pleasing in your sight…. Here was David’s great concern, that his whole person and actions would bring pleasure to God. The believer should not merely be concerned about avoiding offense to God, but he or she should have a positive concern about how to please the living God. If we are made to glorify God and to enjoy him forever, then we ought to recognize that we are not reaching the goal of our being until there is this joint pleasure of God in us and we in him. True Christianity is more than not doing things; it is living in the Lord’s presence in fellowship with him to bring him honor and pleasure and to enjoy all his excellent worth.
O LORD, my Rock and my Redeemer: Here is the focus of David’s life. The God who has spoken in creation and in the holy writings is more than a communicator to David. He is also personally interested in David, and graciously makes himself available to those who trust in him. David views him as his Rock, the one who is able to provide full stability to David’s life, and as his Redeemer, because he had set David free from his sins (see Romans 4). The goal of the Scriptures is to lead us to have fellowship with the living God. David entered into that purpose. Have we?
Grace and peace, David
