“I and the Father are One.” John 10:30 (ESV)
God is three Persons: God the Father, God the Son, and God the Holy Spirit. They are One. God exists in the perfect unity of One. There is never conflict between the three Persons of the Godhead. God is always in perfect harmony with Himself. He is always in perfect unity with Himself. So, after the crucifixion, God raised Jesus from the dead. This was the action of one God in three persons.
Concerning the Father’s role in the resurrection, the Bible teaches: “the immeasurable greatness of his power toward us who believe, according to the working of his great might that he worked in Christ when he raised him from the dead and seated him at his right hand in the heavenly places, far above all rule and authority and power and dominion, and above every name that is named, not only in this age but also in the one to come.” (Ephesians 1:19–21)
Concerning Jesus’s role in His own resurrection, Jesus declared: “For this reason, the Father loves Me, because I lay down My life that I may take it up again. No one takes it from me, but I lay it down of my own accord. I have authority to lay it down, and I have authority to take it up again. This charge I have received from my Father.” (John 10:17-18)
Concerning the Holy Spirit’s role in the resurrection, Paul wrote: “The Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you.” (Romans 8:11)
The Trinity secures the believer’s hope. We know through the action of the Godhead that Jesus’s sacrifice on the cross was efficient and sufficient to secure the salvation of all those who believe Jesus. We never have to question whether Jesus’s death and resurrection were enough to secure our hope. The Father approves Jesus’s work, and is therefore pleased to adopt us, calling us sons and daughters. The Son is satisfied with His own work and is therefore pleased to call us His bride and to share His divine inheritance with us for eternity. The Holy Spirit approves of Jesus’s work and is therefore pleased to indwell us and cause us to believe Jesus and His finished work. The Trinity exists in perfect unity and harmony.
