What is the significance of saying 'Salvation belongeth unto the Lord'?

The phrase 'Salvation belongeth unto the Lord' serves as a profound declaration of God's sovereignty and the exclusivity of His redemptive plan. It emphasizes that salvation is not a human achievement but a divine act initiated and fulfilled by God (Philippians 1:6). His sovereign grace ensures that He chooses, redeems, and preserves His people for eternity. This is crucial in understanding the grace-filled nature of the Gospel: it is God's blessing upon those He has chosen that equips them for salvation. Additionally, it underscores the futility of any attempt at self-salvation, as illustrated by Isaiah 44:20, which depicts humanity's spiritual blindness and inability to save themselves. Thus, acknowledging this truth also fosters gratitude among believers for the grace they have received.
