Isaiah 44:1-2. ” Yet now hear, O Jacob My servant; and Israel, whom I have chosen: Thus saith the Lord that made thee, and formed thee from the womb, which will help thee; Fear not, O Jacob, My servant; and thou, Jesurun, whom I have chosen.”
This prophecy, as yet unfulfilled, is God’s promise that in spite of their suffering, He will not forsake them. They will be restored.
Isaiah showed no difference in this passage between Jacob, Israel, and Judah. Jesurun,in verse 2, means the upright one. The same word is rendered Jeshurun in Deut. 32:15. It is a symbolic name of Israel. God Himself recognized Israel as justified and upright in His sight at first. Afterward, the nation forsook Him, rejected the Rock of their salvation and provoked Him with their sinning to the point that He abhorred them (Deut. 32:15-26).
How could God abhor His own people?
When someone who is deeply loved neglects, rejects, and distorts your love, turning it to his own advantage, becomes abusive, manipulative, and careless toward you, that is abhorrent behavior. God abhorred their behavior as time after time His people repeated the sin of idolatry, forsaking the One Who had brought them out of slavery and promised them their own land.
Rather than asking how He could abhor them, I think it would be more to the point to ask how He could continue, through the centuries, to love them, redeem them, keep His promises to them. And not just to them, but to all who have professed belief in Him and then gone their own way, forsaking the One Who died in their place.
The patience and mercy of God is always amazing to me.
