In between the Apostle Paul’s letter to the Colossians and his first letter to the Thessalonians we read one Psalm and two chapters of Isaiah.
Psalm 89, of Ethan the Ezrahite. “I will sing of the mercies of the LORD forever“. A Psalm of praise to God and His covenant with David, His glory and holiness, His faithfulness to deliver His promises, but also the trouble with the unfaithful. It ends up with a plea for a speedy restoration.
Isaiah 43 speaks of the redeemer and the rebirth of Israel. This happened in 1948, and it happened in spite of Israel’s unfaithfulness only by God’s mercy, and His promise that He would do a new thing.
Isaiah 44. Israel is the chosen nation, God is supreme, idols are worthless. Sing, for the LORD has done it. God is the one “That saith of Cyrus, He is my shepherd, and shall perform all my pleasure: even saying to Jerusalem, Thou shalt be built; and to the temple, Thy foundation shall be laid.”
