The city of our God

Zion

Zion

Glorious things of thee are spoken

Zion, city of our God

He, whose word cannot be broken

Formed thee for His own abode

On the Rock of Ages founded

What can shake thy sure repose?

With salvation's walls surrounded

Thou may'st smile at all thy foes

See, the streams of living waters

Springing from eternal love

Well supply thy sons and daughters

And all fear of want remove

Who can faint, while such a river

Ever flows their thirst to assuage?

Grace which, like the Lord, the giver

Never fails from age to age

Blest inhabitants of Zion

Purchased by the Saviour's blood

Jesus, whom their souls rely on

Makes them kings and priests to God

While in love his Saints he raises

With himself to reign as King

All, as priests, his solemn praises

For thank-off'rings freely bring

Savior, if in Zion's city

I, through grace, a member am

Let the world deride or pity

I will glory in Thy name

Fading is the sinner's pleasure

All his boasted pomp and show

Solid joys and lasting treasure

None but Zion's children know

Hebrews 12:22–24 NIV

But you have come to Mount Zion, to the city of the living God, the heavenly Jerusalem. You have come to thousands upon thousands of angels in joyful assembly, to the church of the firstborn, whose names are written in heaven. You have come to God, the Judge of all, to the spirits of the righteous made perfect, to Jesus the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.

When the writer wrote the words which described the two mountains, it is clear that he had in mind much more than than physical historical mountains. It is doubtful whether any of his readers had ever seen or been anywhere near Mount Sinai, but the mention of it brought to mind the Law and the Giving of the Law. Everything connected with that was fearful and terrifying.
