Charles Spurgeon Commentary Isaiah 54:9-10

"For this is [as] the waters of Noah unto me; for as I have sworn that the waters of Noah shall no more go over the earth, so have I sworn that I will not be wroth with thee, nor rebuke thee. For the mountains may depart, and the hills be removed; but my lovingkindness shall not depart from thee, neither shall my covenant of peace be removed, saith Jehovah that hath mercy on thee." — Isaiah 54:9-10 (ASV)

For this is as the waters of Noah unto me: for as I have sworn that the waters of Noah should no more go over the earth; so have I sworn that would not be wroth with thee, nor rebuke thee. For the mountains shall depart, and the hills be removed; but my kindness shall not depart from thee, neither shall the covenant of my peace be removed, saith the LORD that hath mercy on thee.

Oh, for grace, oh, for the help of the Holy Spirit to lay hold of these precious promises, and to feed on them!

For this is as the waters of Noah unto me: for as I have sworn that the waters of Noah should no more go over the earth; so have I sworn that I would not be wroth with thee, nor rebuke thee. For the mountains shall depart, and the hills be removed;

There is nothing really stable about them; all things that are visible must melt and flow away.

For this is as the waters of Noah unto me: for as I have sworn that the waters of Noah should no more go over the earth; so have I sworn that I would not be wroth with thee, nor rebuke thee. For the mountains shall depart, and the hills be removed; but my kindness shall not depart from thee, neither shall the covenant of my peace be removed, saith the LORD that hath mercy on thee.

What more can he say than to you he has said? What surer pledges can he give? Oh! rest, rest, rest, sweetly rest, on this sure word of covenant love. Then let the mountains move. He told you they would. Then let the hills of your comfort sink. He told you they would. But even then, when earth itself reels, and the very pillars of the universe are snapped, he stands still the same. I have sworn that I would not be wroth with thee, nor rebuke thee.
