The Holiness of God
Sermon on Psalm 99
“The Lord Our God Is Holy”
Text: Psalm 99
Psalm 99 lifts our eyes from the troubles of earth to the throne of heaven. It reminds us that God is still reigning. Nations may be in turmoil, governments may change, and the world may seem uncertain, but the Lord remains on His throne. Three times in this psalm we are told, “He is holy.” Holiness is the great theme of this psalm.
The Lord Reigns
“The Lord reigneth; let the people tremble.”
God has never surrendered His throne. He has never been defeated, surprised, or overwhelmed by the events of history. Every king, president, prime minister, and ruler is temporary, but the Lord reigns forever.
That truth should give the believer confidence. We do not worship a defeated God. We worship the King of kings and Lord of lords.
When life feels uncertain, remember that heaven has not changed. God is still in control.
God’s Holiness
The angels around God’s throne cry continually,
“Holy, holy, holy.”
Holiness means that God is completely pure, righteous, and separate from sin. There is no darkness in Him, no injustice, no deceit, and no corruption.
The closer Isaiah came to God, the more he saw his own sin and cried,
“Woe is me!”
The closer we walk with God, the less we boast about ourselves and the more we admire His holiness.
God Loves Justice
Verse four tells us that the King loves judgment and establishes equity.
Our world often seems unfair. The innocent suffer while evil appears to prosper. But God’s justice is perfect. Nothing escapes His notice.
Every hidden act, every spoken word, every secret thought is known by Him.
One day the Judge of all the earth will do right.
For the Christian, this is a comfort. For the unbeliever, it is a solemn warning.
God Hears Prayer
Moses, Aaron, and Samuel are mentioned because they called upon the Lord, and He answered them.
God still hears prayer.
He hears the cry of the broken-hearted.
He hears the lonely.
He hears the sinner who comes in repentance.
He hears the saint who seeks His face.
Prayer is not a religious exercise—it is speaking to the living God.
The throne described in Psalm 99 is not closed to God’s children. Through Jesus Christ we may come boldly to the throne of grace.
God’s Mercy and Discipline
Verse eight says,
“Thou wast a God that forgavest them, though thou tookest vengeance of their inventions.”
God forgives, but He also disciplines.
A loving father corrects his children because he loves them.
Sometimes God’s discipline is painful, but it is always purposeful. He shapes us into the likeness of Christ.
The cross proves both God’s justice and God’s mercy.
Justice demanded that sin be punished.
Mercy provided Jesus to bear that punishment in our place.
Worship the Holy God
The psalm ends,
“Exalt the Lord our God, and worship at his holy hill; for the Lord our God is holy.”
Worship is more than singing hymns.
It is surrender.
It is obedience.
It is living every day to honour Christ.
When we truly understand God’s holiness, worship becomes natural.
Conclusion
Psalm 99 reminds us that God still reigns.
His throne is secure.
His justice is perfect.
His mercy is abundant.
His ears are open to prayer.
His holiness never changes.
In a changing world, we serve an unchanging God.
So let us exalt Him.
Let us trust Him.
Let us obey Him.
Let us worship Him.
For the Lord our God is holy.
Amen.
GOD IS A GOOD GOD
