God must and did give His Son all the hellish agony we deserve. And if God had spared Him from that agony, we would have it poured out fully upon us. He can and does call us into being as His children, and gives us that glory. That cross reveals why all things work together for our good, and it opens the door to heavenly blessedness for us. Sing then a new song to Jehovah, for the wonders He has wrought.
Death has no sting, and the grave has no victory.
God uses these for our glory which He promised us. That Blessed Intercession Where Christ is today has tremendous significance. He was here on the earth for 33 years, and then He left this earth to be at God's right hand in heavenly glory. The amazing blessedness thereof is that He is between God and us. That is what it means that He makes intercession for us.
