He drank a cup of poison for us, a cup of eternal poison, that was reserved for us, the foaming cup of God's wrath, so that we would not have a drop of it. He did this so that we would not perish eternally, that our soul would not be forever destroyed, separated from all good forever, but that we would have eternal life, rather than being separated from never seeing His face again. where He would hide His face forever. We will be able to forever behold His face, with His face shining upon us, because the Father turned His face away from His only begotten Son in Christ. God has prevented the greatest and eternal suffering from happening to us by taking that suffering Himself.
