Jesus accomplished the work God sent Him here to do. He did it perfectly, sinlessly, and died on the cross after absorbing all God’s wrath for sin. He even endured a horrific separation from the Father. Jesus had only ever known perfect harmony with God and love and sweet communion. O! To be cruelly dismissed from His presence! Jesus was not afeared of the pain of the crucifixion as much as he was dreading being separated from God. It was the loneliest moment in history forever.
He endured that separation and bore the wrath, so we would never have to. We can come into sweet communion with the Father, justified, sanctified, and someday, glorified.
God was pleased with His Son, and resurrected Him from the dead.
God raised him up, loosing the pangs of death, because it was not possible for him to be held by it. (Acts 2:24)
