How do we know that salvation is entirely a work of grace?

The nature of salvation as a work of grace is confirmed throughout scripture, particularly in Isaiah 43:25, where God declares that He blots out transgressions not because of our merit but for His own sake. This demonstrates that God’s willingness to save and redeem sinners is rooted in His grace and sovereign choice rather than any human effort. The historical context of Israel's rebellion serves as a backdrop to stress that despite their unfaithfulness, God initiates reconciliation. This understanding fosters a dependence on Christ's atoning work rather than our own efforts, highlighting God's initiative in our redemption.
