What does the Bible say about God's promises to His Son?

The promises God the Father makes to His Son are ones of glory and reward for His successful work of redemption, as stated in Isaiah 60. The Father assures His Son that He cannot allow Him to remain in the grave, affirming His resurrection as a pivotal aspect of God's plan for salvation. These promises not only apply to Christ but also extend to the body of believers who are united with Him, symbolizing a shared inheritance in the kingdom of God, thereby demonstrating God’s faithfulness.
