God is my Rock
New Covenant People
King David writes this Psalm as a testimony of God’s power in his life after he became king. His psalms clearly allude to God’s faithfulness when David points out God’s supreme power over all the difficult challenges, threats, wars, drama, betrayal, God’s covenant loyalty, deliverance from the enemy, and God’s display of His power over chaos. The list can go on when we talk about God and His sovereign hand upon His people, with a firm, solid, unquestionable conclusion that God is a Rock and Refuge for His Covenant People. Because of Christ Jesus’ death and resurrection, and our sins being pardoned, we have been given the shield of salvation, and we can be confident that we are His new covenant people, marked by the work of His grace through the blood of the Lamb. In Galatians 3:28–29 (ESV), “If you are Christ’s, then you are Abraham’s offspring, heirs according to promise.” In the New Testament, in Christ by faith, we are included in the covenant of God’s family. This covenant is made possible because of Jesus’ blood “this cup that is poured out for you is the new covenant in my blood” (Luke 22:20 ESV). It is no longer the Jews alone, but the redeemed people of God from across the Nations. All Nations and people groups are included in this powerful covenant when they repent and put their faith in Christ. They are then called the New Covenant people, and that truth will lead to the proclamation, God is my rock and my refuge, and my feet won’t slip.”Now, in this Psalm, I love to see a threefold context:
David’s Situation (Historical), God’s Reality (Theological view of God), and The Audience (Communal and Canonical).
We can also call or see this portion, or the whole Psalm, as three voices in the Psalm: The Voice of the Psalmist, The Voice of God’s Action, and The Voice Addressing God’s People.
The Voice of the Psalmist
David remembers the hand of God in his life while he was battling through many difficult things. His whole life was like a run. God had chosen him; he had skills; he was faithful, a man after God’s own heart, a man who pursued God wholeheartedly and never chased God for benefits. A pure desire was found in David’s heart to seek God. We understand that God chose him to be king and anointed him as a young man to rule Israel. This calling led him to face difficult challenges and hardships in life. In Psalm 18:4, we read, “the cords of death encompassed me.” That doesn’t sound like much fun, does it? Let’s break down all that David went through in the process of becoming king.
A. Persecuted by King Saul: Saul wanted to kill David because he was envious of his skills and leadership. David was also betrayed by towns and informants like the Ziphites.
B. Life in Exile: Hiding in caves, wilderness, and foreign lands (Adullam, En-gedi). A complete dependence on God for daily survival. David had to live outside the normal covenant life for a season. In Psalm 18:27, King David says, “I was brought low, and He saved me.”
C. Military Threats and Warfare: Constant battles with the Philistines and surrounding nations, facing enemies stronger and more numerous than himself. No wonder he says in Psalm 18:39 (ESV), “You equipped me with strength for the battle.”
D. False Accusations and Injustice: Treated as guilty despite innocence: “They confronted me in the day of my calamity” (Psalm 18:18, ESV).
E. Moral Testing: David walked faithfully when tested by injustice. In Psalm 18:21 (ESV), we read, “I have kept the ways of the Lord.”
F. Threats of Death: Near-death experiences repeatedly. In Psalm 18:5, “The snares of death confronted me.” G. Political Instability: Anointed king but living without power or a throne, waiting for God’s vindication. In Psalm 18:19, David says, “He brought me out into a broad place.”
The Voice of God’s Action
Now we can look at the loud voice of God’s action, a glimpse of a faithful God who keeps His covenant with His anointed one. This section also helps us see the reality of God’s nature, summed up in one sentence: God is a Rock for His covenant people. God does not merely speak or give vain hope; He acts justly and is quick to help His people.
Verse 29 – “By my God, I can leap over a wall.”
Verse 30 – “He is a shield.”
Verse 31 – “Who is a Rock?”
Verse 35 – “The shield of Your salvation.”
Verse 35 – “Your gentleness made me great.”
Verse 28 – “The Lord my God lightens my darkness.”
In verse 28, we note that God’s actions reveal that He empowers His people with light. Sometimes people find themselves in situations where they cannot see a way out and need direction into the path of life. Here is the good news: there is hope. Just as God enlightened David’s steps, He will help you see the path as well. God will empower you through His Word and through His servants to help you navigate dark seasons—spiritual illumination through His spoken Word and pastoral counsel.
Verse 29 – “By my God I can leap over a wall.”
This verse reminds us that God removes obstacles. Not that we avoid walls, but we face them while worshiping God. Just as the walls of Jericho fell, so God can break down barriers when we run to Him, worship Him, and cry out for help. What seems impossible becomes possible through God’s supernatural power.
Verse 30 – “He is a shield.”
God protects His covenant people. David declares that God was his shield against adversaries and darkness. God’s Word is pure; what God does flows from who God, faithful and dependable. In Ephesians 6, Paul speaks of the shield of faith that protects us from the enemy’s attacks—doubt, fear, temptation, and uncertainty. In all circumstances, take up the shield of faith, trusting that God’s promises will come to pass.
Verse 31 – “Who is a Rock?”
This verse forms the climax of the Psalm. David asks, “Who is God?” and answers by calling Him Rock. Who is God to you? Our answer is often revealed in times of difficulty. I encourage you to look to God as your refuge. He can deliver you from anything.
Psalm 20 (ESV): “May the Lord answer you in the day of trouble! May the name of the God of Jacob protect you! May He send you help from the sanctuary and give you support from Zion! May He remember all your offerings and regard with favor your burnt sacrifices! May He grant you your heart’s desire and fulfill all your plans! May we shout for joy over your salvation, and in the name of our God set up our banners! Some trust in chariots and some in horses, but we trust in the name of the Lord our God.” Amen
Verse 35 – “Your Gentleness made me Great”
The beauty of this Psalm is found in verse 35, where David calls God gentle. In His gentleness, God makes His covenant people great. God’s power is displayed through meekness and grace. In Matthew 11:29, Jesus says, “I am gentle and lowly in heart, and you will find rest for your souls.” We do not serve a harsh God; we serve a good and beautiful God. Trust Him in difficult times. Walk faithfully, and in His gentleness, He will make you great according to His purposes.
