God deals with sin through judgment for the unrepentant and grace for His chosen remnant, ultimately fulfilled in Christ.
Isaiah presents a clear view of God's righteous judgment against sin. In Isaiah 1:4, the people are called a 'sinful nation, laden with iniquity.' Throughout the book, God expresses that all will face consequences for rebellion against Him, as stated in Isaiah 66:15-16. However, God also reveals His plan to save a remnant, underscoring the Gospel message of grace amidst judgment. This is epitomized in Isaiah 1:18, where God invites the repentant to reason together, promising forgiveness. The ultimate solution for sin, as depicted in Isaiah, is fulfilled in Christ, who bears our sins and provides atonement, thus satisfying God's justice while extending grace to the redeemed. This duality of judgment and mercy is foundational to understanding God's character towards sin.
