Summary
Psalm 51 reveals our need for inner renewal, not outward reform. Human hearts are deceitful and require God’s cleansing, steadfast spirit, and restoring joy. Sin disrupts joy and worship, but repentance brings forgiveness and renewed purpose. Only after God cleanses us can we teach others His ways. True worship is a humble, broken heart surrendered to God, not a religious effort.
Why We Need a Complete Spiritual Overhaul
We need a complete spiritual overhaul to serve others because we love them as we love ourselves. We need a clean, morally pure heart (Psalm 51:10) to love and truly worship God.
Our intellect, emotions, and will all need God’s tuning. God is still working on us. We are not finished products yet.
The Deceptive Human Heart
Some think they have always been morally upright. They are deceiving themselves. Jeremiah 17:9 (NIV) says, “The heart is deceitful above all things and beyond cure. Who can understand it?”
A Clean Heart and Renewed Spirit
My former neighbor’s hand water pump produced rusty and muddy-looking liquid. A new coat of paint on the outside of the pump would not make the water any clearer.
Doing the “right” thing is not enough. We need a clean heart. Only God can create it.
We need a steadfast spirit (Psalm 51:10). We are like weathervanes in the wind. We too readily align with evil influences. Only God can make us firm and unwavering in doing what is right with the right attitude, no matter how the wind of circumstances blows. We need a clean heart and a renewed spirit.
David was king because God had chosen him. After sinning, he feared God would reject him as He had rejected King Saul.
The Holy Spirit had come upon David at his anointing (1 Samuel 16:13). He begged God not to remove the Holy Spirit from him.
Joy, Repentance, and Restoration
Salvation naturally brings abounding delight. Psalm 51 suggests that the absence of joy often indicates the presence of sin.
The principle applies to us as much as to King David. Joy returns after we repent and confess our sins to God.
Forgiven People Who Teach Others
After God had forgiven him, David said he would teach transgressors God’s ways and convert sinners to Himself (Psalm 51:13). We can only teach transgressors God’s ways after God has blotted out our transgressions.
Christian education is often ineffective because half-hearted teachers instruct quarter-hearted students about things neither wants to practice. When teachers and students turn away from their sins, sinners will turn to God.
We cannot ignore our guilt (Psalm 51:14). David pleads for God’s unmerited forgiveness apart from special sacrifices or works on his part. In Romans 3:26, we learn that God is both just and the justifier of those who believe in Jesus.
God must open our lips to praise Him. We can then exalt who He is and what He has done wherever we are.
True Worship: A Broken and Humble Heart
God is not asking us to give up anything except our sins. A tender, humble, broken heart is the best thank offering and an act of worship. See additional free spiritual growth resources for Christians.
God has empowered me to write His Power for Your Weakness—260 Steps Toward Spiritual Strength. It’s a free, evangelistic, devotional, and discipleship e-book. Pastors have used it in Malawi, Mozambique, and Zambia to lead 7,590 people to Christ and teach the basics of Christianity to 17,681 people. I invite you to explore and use it in your setting.
