Look how the prayer comes to its climax in verses 18b–19:
“We do not present our supplications before thee on the ground of our righteousness but on the ground of thy great mercy. O Lord, hear; O Lord, forgive; O Lord, give heed and act; delay not, for thy own sake, O my God, because thy city and thy people are called by thy name.”
The people of God are known by his name. And God has an infinite zeal for his own name. He will not let it be reproached and made a byword indefinitely. That is our deepest confidence. God is committed to God. God is committed with explosive passion to the glory of his name and the truth of his reputation.
So that’s the bottom of our prayer for a desolate church. We are called by your name. We live by your name. Not to us, O Lord, not to us, but to your name give glory. For your name’s sake, O Lord, save. For your name’s sake, revive. For your name’s sake purify and heal and empower your church, O Lord. For we are called by your name.
