What does the Bible say about Christ as a Testator?

The concept of Christ as a Testator is deeply embedded in Scripture, particularly in Hebrews 9:16-17, which asserts that where a testament exists, the death of the Testator is essential for it to take effect. This can be compared to earthly testators who provide for their loved ones through their wills. Christ, as the spiritual Testator, has all the riches of grace and glory, and through His death, He ensures that His blessings are secured for His elect. His last will and testament establish the covenant of grace, highlighting the importance of His sacrificial death in guaranteeing the promises made to His followers.
