Skeptic asked: “If Jesus could not save Himself, how can He save you?“
Jesus, God in flesh, could have rejected the Father’s will and permitted the Devil to have victory over your sinful soul and thereby allowed you to die in Hell without hope but Jesus, even though horrified by the Cross and spiritual separation from the Father, endured unconscionable beating and suffocation upon a Roman Cross in order that His innocent blood would be shed as atonement for your sin (Matthew 26:28; Leviticus 17:11; Hebrews 9:22). Jesus performed this sacrificial act out of selfless love for the Father and the Father’s will for you and your eternity.
Don’t disparage what God has done for you within the Realm of Time so that you can attain victory over the Devil as God is restoring peace and order to His Kingdom that was ravaged by the Devil’s rebellion. Don’t die as a subject of the Devil but die in body in victory in Jesus and live with God forever in that victory (John 3). Trust – believe in Jesus as your Lord and believe that Jesus died for you to pay your sin-debt owed the Father and live with God, forever, in peace (John 14:6; John 3; Romans 5:1).
