8 In overflowing anger for a moment I hid my face from you, but with everlasting love I will have compassion on you," says the Lord, your Redeemer. 9 "This is like the days of Noah[1] to me: as I swore that the waters of Noah should no more go over the earth, so I have sworn that I will not be angry with you, and will not rebuke you. 10 For the mountains may depart and the hills be removed, but my steadfast love shall not depart from you, and my covenant of peace shall not be removed," says the Lord, who has compassion on you.

Commentary on Isaiah 54:6-10
(Read Isaiah 54:6-10)
As God is slow to anger, so he is swift to show mercy. And how sweet the returns of mercy would be, when God should come and comfort them! He will have mercy on them. God's gathering his people takes rise from his mercy, not any merit of theirs; and it is with great mercies, with everlasting kindness. The wrath is little, the mercies great; the wrath for a moment, the kindness everlasting. We are neither to despond under afflictions, nor to despair of relief. Mountains have been shaken and removed, but the promises of God never were broken by any event. Mountains and hills also signify great men. Creature-confidences shall fail; but when our friends fail us, our God does not. All this is alike applicable to the church at large, and to each believer. God will rebuke and correct his people for sins; but he will not cast them off. Let this encourage us to give the more diligence to make our calling and election sure.
