Psalm 103:11 NKJV


How Great is God’s Mercy?

How do you measure mercy? David reaches for the most limitless comparison imaginable — the heavens themselves. “As the heavens are high above the earth,” he says. Stand beneath a midnight sky and look up. The stars stretch out farther than the eye can see, farther than the telescope can measure. That’s the picture David paints of God’s mercy — boundless, immeasurable, inexhaustible.

God’s mercy towers above our failures the way the heavens tower above the earth. Every time you’ve stumbled and turned back to Him, every tear you’ve cried in repentance, every moment you’ve feared you’d gone too far — this is the mercy that met you there. If you could somehow scale the distance between heaven and earth, you would still fall infinitely short of the height of His compassion.

The Hebrew text suggests that God’s mercy isn’t just “big”; it prevails over us. It’s like the waters of the flood in Genesis that rose above the highest mountains. But instead of a flood of judgment, this is a flood of grace. It towers over our sins, our failures, and even our best attempts at being “good.” As one commentator noted, the earth is but a tiny point compared to the vast expanse of the heavens. In the same way, our merits—the things we do to try to please God—are microscopic compared to the height of His favor.

But notice the qualifier David gives: “toward those who fear Him.” God’s mercy is not a blanket permission to live without reverence; it’s a sacred gift for those who honor and love Him. To “fear” the Lord doesn’t mean to live terrified, but to live aware — aware of His holiness, His greatness, His goodness. It is a posture of awe that keeps pride at bay and softens the heart to grace.

Spurgeon described it beautifully: “As the lofty heavens canopy the earth… so the Lord’s mercy from above covers His chosen, enriches them, embraces them.” Just as the atmosphere surrounds the globe, God’s mercy surrounds His people — protecting, nourishing, and sustaining life in unseen ways each day.

The more deeply you grasp this, the more humbly you walk. You cannot earn or exhaust this mercy. You can only receive it — with reverence, with gratitude, and with wonder at how wide the arms of God’s compassion truly are.

  • Mercy is beyond measure. Just as we cannot reach the furthest star, we cannot exhaust the depths of God’s forgiveness.
  • A “Prevailing” Grace. God’s mercy doesn’t just meet our sins; it overflows and rises above them.
  • The Heart of Reverence. Biblical “fear” isn’t terror; it is a profound respect that draws us closer to God rather than driving us away.
  • Universal Coverage. Like the sky, God’s mercy is always present and “over” His children, regardless of their location or circumstance.
  • Genesis 32:10: “I am not worthy of the least of all the mercies and of all the truth which You have shown Your servant; for I crossed over this Jordan with my staff, and now I have become two companies.”
  • Psalm 36:5: “Your mercy, O Lord, is in the heavens; Your faithfulness reaches to the clouds.”
  • Psalm 115:11: “You who fear the Lord, trust in the Lord; He is their help and their shield.”
  • Micah 7:18: ” Who is a God like You, Pardoning iniquity And passing over the transgression of the remnant of His heritage? He does not retain His anger forever, Because He delights in mercy.”
  • Genesis 7:18: “The waters prevailed and greatly increased on the earth, and the ark moved about on the surface of the waters.” 
  1. When you think of the distance between the “heavens and the earth,” how does that scale change the way you view your biggest mistake?
  2. What does “fearing the Lord” look like in your daily life? Is it more of a “reverent awe” or a “fear of punishment”? 
  3. In what area of your life do you feel you need God’s mercy to “prevail” or overflow right now?
  4. If God’s mercy is like the heavens (giving rain, sun, and protection), what “blessings of mercy” have you noticed in your life this week?

“The Lord bless you and keep you; The Lord make His face shine upon you, And be gracious to you; The Lord lift up His countenance upon you, And give you peace.” Numbers 6:24-26 NKJV

Grace be with you. Amen.

Psalm 103:11 illustrates God’s boundless mercy using the greatest conceivable distance: the height of the heavens above the earth. Commentators like Spurgeon and Henry emphasize that this grace is immeasurable, transcendent, and “prevails” over our sins. While infinite in scale, this mercy is specifically promised to those who “fear Him”—those who approach God with humble reverence. Ultimately, His compassion exceeds all human merit, offering inexhaustible support, consolation, and forgiveness to the faithful.

Charles Spurgeon

For as the heaven is high above the earth, so great is his mercy toward them that fear him.” Boundless in extent towards his chosen is the mercy of the Lord; it is no more to be measured than the height of heaven or the heaven of heavens. “Like the height of the heaven” is the original language, which implies other points of comparison besides extent, and suggests sublimity, grandeur, and glory. As the lofty heavens canopy the earth, water it with dews and rains, enlighten it with sun, moon, and stars, and look down upon it with unceasing watchfulness, even so the Lord’s mercy from above covers all his chosen, enriches them, embraces them, and stands for ever as their dwelling place. The idea of our version is a very noble one, for who shall tell how exceeding great is the height of heaven? Who can reach the first of the fixed stars, and who can measure the utmost bounds of the starry universe? Yet so great is his mercy! Oh, that great little word so! All this mercy is for “them that fear him;” there must be a humble, hearty reverence of his authority, or we cannot taste of his grace. Godly fear is one of the first products of the divine life in us; it is the beginning of wisdom, yet it fully ensures to its possessor all the benefits of divine mercy, and is, indeed, here and elsewhere, employed to set forth the whole of true religion. Many a true child of God is full of filial fear, and yet at the same time stands trembling as to his acceptance with God; this trembling is groundless, but it is infinitely to be preferred to that baseborn presumption, which incites men to boast of their adoption and consequent security, when all the while they are in the gall of bitterness. Those who are presuming upon the infinite extent of divine mercy should here be led to consider that although it is wide as the horizon and high as the stars, yet it is only meant for them that fear the Lord, and as for obstinate rebels, they shall have justice without mercy measured out to them.

For as the heavens are high above the earth: This is a description of the abounding mercy of God mentioned in Psalm 103:8. The distance from the earth to the heavens measures the greatness of His mercy toward those who fear Him. By instinct, we often think of God’s mercy as less than it really is. (Guzik)

i. There were three concepts of heaven in the ancient Biblical world. The first heaven is the blue sky, the atmosphere with its sun. The second heaven is the night sky, the stars, and constellations. The third heaven is the place where God dwells and is enthroned. It’s interesting to wonder which of the three concepts of heaven David had in mind with this wonderful statement. (Guzik)

For as the heaven is high above the earth – See the notes at Psalms 57:10. Compare the notes at Isaiah 55:9. The literal translation of the phrase here would be, “For like the height of the heavens above the earth.” The heavens – the starry heavens – are the highest objects of which we have any knowledge; and hence, the comparison is used to denote the great mercy of God – meaning that it is as great as can be conceived; that there is nothing beyond it; that we cannot imagine that it could be greater – as we can imagine nothing higher than the heavens.

So great is his mercy toward them that fear him – To those who reverence and serve him. That is, His mercy is thus great in forgiving their offenses; in imparting grace; in giving them support and consolation.

For as the heaven is high above the earth,…. Which is the greatest distance known, or can be conceived of? The space between the heaven and the earth is seemingly almost infinite, and nothing can more illustrate the mercy of God, which reaches to the heavens, and is in heaven; though this is but a faint representation of the largeness and abundance of it, and which indeed is boundless and infinite:

So great is his mercy towards them that fear him, or his mercy hath prevailed over them that fear him; as the waters of the flood prevailed upon the earth, and reached and overflowed the highest hills, Genesis 7:18, so abundant and superabundant is the grace of God over them that “fear” him. Which character is given, not as being the cause of their obtaining mercy, but as descriptive of the persons that partake of it; on whom it has such an effect, as to cause them to fear the Lord, and his goodness; and is mentioned to prevent obstinate and presumptuous sinners expecting it, or trusting to it.

Matthew Henry

The transcendent riches of God’s mercy (v. 11): As the heaven is high above the earth (so high that the earth is but a point to the vast expanse), so God’s mercy is above the merits of those that fear him most, so much above and beyond them that there is no proportion at all between them; the greatest performances of man’s duty cannot demand the least tokens of God’s favour as a debt, and therefore all the seed of Jacob will join with him in owning themselves less than the least of all God’s mercies, Gen. 32:10. Observe, God’s mercy is thus great towards those that fear him, not towards those that trifle with him. We must fear the Lord and his goodness.

Our mind cannot find a comparison too large for expressing the superabundant mercy of the Lord toward his people.
