Isaiah 63, 64

The reading of Isaiah 64 rings in the heart of every Christian as a plea for God to show up in His supernatural power.

Oh, that You would tear open the heavens and come down,
That the mountains would quake at Your presence—

Later in the passage, the key to seeing this kind of power is …

(You God), Who acts in behalf of one who waits for You.
You meet him who rejoices in doing righteousness,
Who remembers You in Your ways. [NASB]
