God's promise to save His people is guaranteed through the covenant established by Jesus, who laid down His life and rose again.
The assurance of salvation for God's people is rooted in the everlasting covenant initiated through Jesus Christ, as described in Hebrews 13:20. This covenant outlines God's commitment to redeem His chosen ones. Jesus’ death and resurrection serve as the definitive proof of this promise; He laid down His life for the sheep and ensures that His will for salvation is accomplished (Romans 5:1). Therefore, all that the Father gives to the Son will come to Him, illustrating the effectiveness of His atoning sacrifice. Hence, God's glory is tied to the successful salvation of His people, affirming that they cannot ultimately be lost.
