Because Israel thought they could keep a portion of their lives under their own control rather than submitting it all to God, he placed them under judgment. But through judgment, God washed away this notion, along with their sin. God then foretells that those who were left in the land were going to be a testimony to the surety of his covenant promises (Vs 2), and a testimony of God's redemptive power (Vs. 3-4). Like Israel, we should recognize that true holiness will only come when we are completely reliant on Christ's finished work of salvation, and abandon our own limited and faulty notions of self-centered religion. If you are a believer, he promises to renew, restore, and dwell with you. Are you suffering? Pursue God and dedicate yourself to resting in God's willingness to work our salvation and sanctification in your life.
Isaiah 4 English Standard Version (ESV)
4 And seven women shall take hold of one man in that day, saying, “We will eat our own bread and wear our own clothes, only let us be called by your name; take away our reproach.”
The Branch of the Lord Glorified
2 In that day the branch of the Lord shall be beautiful and glorious, and the fruit of the land shall be the pride and honor of the survivors of Israel. 3 And he who is left in Zion and remains in Jerusalem will be called holy, everyone who has been recorded for life in Jerusalem,4 when the Lord shall have washed away the filth of the daughters of Zion and cleansed the bloodstains of Jerusalem from its midst by a spirit of judgment and by a spirit of burning.[a] 5 Then the Lord will create over the whole site of Mount Zion and over her assemblies a cloud by day, and smoke and the shining of a flaming fire by night; for over all the glory there will be a canopy. 6 There will be a booth for shade by day from the heat, and for a refuge and a shelter from the storm and rain.
