What does Isaiah 17:7 mean?

In this verse, Isaiah describes the purpose of the Lord's judgment on His people. Once they have been stripped of everything else, He wants them to turn back to Him. He wants them to put their faith and trust in Him to provide all they need and so much more. Following the Lord's harsh judgment through the Assyrians, the tiny remnant in Israel will finally look to their Maker. They will finally acknowledge the Creator of all things, the Holy One of Israel. Boiled down to its very essence, humility begins with the creature bowing before its creator. The core of humility is human beings bowing before the Lord who made the heavens and the earth and all that lives within them.

The Lord's desire for His people remains the same in this generation, as well. He continues to discipline those He loves, as a good Father, to turn our attention from worthless things and return our attention to Him. "For the moment all discipline seems painful rather than pleasant, but later it yields the peaceful fruit of righteousness to those who have been trained by it." (Hebrews 12:11)
