Isaiah 54:10 Though the mountains be shaken and the hills be removed, yet my unfailing love for you will not be shaken nor my covenant of peace be removed,” says the LORD, who has compassion on you.

Isaiah 54:1–17: Today’s reading describes the LORD’s love for and relationship with Israel and his promise to rebuild Jerusalem. The opening verses affirm that Jerusalem will once again be filled with people. The Lord Almighty will again show compassion and everlasting kindness to His rejected bride. His unfailing love and covenant of peace cannot be shaken or removed.

What does it mean? God’s promise of Jerusalem’s future peace and glory in the millennial kingdom was comforting to His people. Despite being rejected and estranged for years, the Lord will restore His holy city and chosen people. Israel will yet experience the salvation of the Lord. Throughout this passage, God’s description of Himself shows how and why such a restoration is possible. He is their Maker, husband, the Lord Almighty, Holy One of Israel, Redeemer, and God of all the earth. As such, He keeps His covenant of peace and shows unfailing love, deep compassion, and everlasting kindness.

The covenant of my peace; that covenant whereby I have made peace and friendship with thee, and have promised unto thee all manner of happiness, which frequently comes under the name of peace in Scripture. The sense of the place is, that God will not cast off his Christian church, as he did cast off the church of the Jews; and that the new covenant is established upon better and surer promises than the old, as is observed,-Bible Hub

Creature-confidence 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. Bible Hub
