When Jesus had received the sour wine, he said, “It is finished,” and he bowed his head and gave up his spirit, (John 19:30, ESV).
Atonement had been made at that moment in human history. In the crucifixion of Jesus Christ, the justice, holiness, righteousness and wrath of God was satisfied.
Done. His work complete. No further atonement was needed. Salvation was fully secured at that moment – finished. Which is why the author of Hebrews could say “after making purification for sins, he sat down at the right hand of the Majesty on high,” (Hebrews 1:3, ESV).
His work is finished. Thank you Jesus!
