How does God's unchangeable nature affect redemption?

God's works are permanent, and this includes His Redemptive work in Christ. As emphasized in the sermon, if God has redeemed His people, that redemption is full and complete, not subject to change. The finished work of Christ on the cross secures salvation irrevocably, as mentioned in the statement, 'Not one soul He redeemed with His precious blood will ever be lost.' This reflects the assurance that our standing before God is not based on our fluctuating deeds but on His faithful and unchangeable promise.
