God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
The penalty for sin is determined by the magnitude of the one who is sinned against. If you sin against a log, you are not very guilty. On the other hand, if you sin against a man or a woman, then you are absolutely guilty. And ultimately, if you sin against a holy and eternal God, you are definitely guilty and worthy of eternal punishment.
[Jesus Christ] did not ransom everybody. He gave his life a ransom for many (Mark 10:45). He did not propitiate the wrath of God against everybody. But He laid down His life for the sheep. They are scattered throughout the world in every tongue and tribe and people and nation.
