The straight forward answer is that God raised Jesus from the dead as Acts 2:24 states: “God raised him up, loosing the pangs of death, because it was not possible for him to be held by it.”
But I love the trinitarian implications found in Scripture with respect to Christ’s resurrection.
Most references to God raising Jesus up refer to God the Father. Even the mockers testified truth when they said in Matthew 27:43: “He trusts in God; let God deliver him now, if he desires him. For he said, ‘I am the Son of God.’” The Father-Son relationship was validated by the resurrection, and God the Father proved to be faithful in resurrecting Jesus.
Scripture also gives us evidence that Christ’s power was involved in the resurrection, as Jesus is the Second Person of the Trinity. In John 11:25 Jesus makes the powerful statement “I am the resurrection and the life,” assuming to Himself the power to life. Jesus also said in John 10:17-18, “I lay down my life that I may take it up again… I have authority to lay it down, and I have authority to take it up again. This charge I have received from my Father.”
The Father has assigned the task of life to the Son.
The Holy Spirit is also closely implicated in the greatest and most important event to ever grace the face of the universe. Romans 1:4 says that Jesus “was declared to be the Son of God in power according to the Spirit of holiness by his resurrection from the dead.” And Romans 8:11 makes it clear that the work of the Holy Spirit in bringing us to life is similar to the work of resurrecting Jesus: “If 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.”
The Father, Son, and the Holy Spirit have achieved the greatest and most glorious act in this work of redemption when Jesus was resurrected.
And we rejoice as we look forward to God resurrecting up His saints in a similar fashion!
