How do we know salvation is a work of God's grace?

The narrative of Israel’s deliverance from Egypt teaches us that salvation is not a result of human effort or decision-making, but solely of God's grace. The Israelites were in bondage, unable to liberate themselves, just as humanity is bound by sin and cannot attain salvation by their own merits. Through God's intervention in the form of plagues, He exemplifies that it is only by His sovereign grace that we are freed from our captors, sin and Satan. Moreover, the Passover lamb serves as a foreshadowing of Christ, whose sacrifice provides the ultimate means of our deliverance. Therefore, the doctrine of sovereign grace assures us that if God saves, He receives all the glory, which is foundational to understanding redemption in Christ.
