Yes indeed, it's because of Christ. The resurrection of the saints will be exciting!
We now have earthly bodies, but we will soon have glorified bodies that won't stay in any tomb anywhere. Sure, as described in Scripture for Christians. This change won't be a mere upgrade of our current physical form as we understand upgrades, but we each will be transformed into something perfectly fit for eternal life with God.
In context let's meditate upon..
1 Cor. 15:12-20, 1 Corinthians 15:35–41, 1 Corinthians 15:50–58, John 10:17, 18
The Trinity was involved in raising up Jesus, yes, Christ himself though dead was also involved in rasing himself out of that borrowed tomb.
"The words “it was credited to him” were written not for him alone, 24 but also for us, to whom God will credit righteousness—for us who believe in him who raised Jesus our Lord from the dead. 25 He was delivered over to death for our sins and was raised to life for our justification." Rom. 4:23-25 niv
"..for our benefit, too, assuring us that God will also count us as righteous if we believe in him, the one who raised Jesus our Lord from the dead. He was handed over to die because of our sins, and he was raised to life to make us right with God." Rom. 4:24-25 nlt
And now because Christ lives, we too shall live with Him (John 14:19).
Jesus said, "Soon the world will no longer see me, but you will see me. Since I live, you also will live." Jn. 14:19 nlt
"The God of our fathers raised up Jesus, whom you had put to death by hanging Him on a cross. He is the one whom God exalted to His right hand as a Prince and a Savior, to grant repentance.." And why? It was for a good purpose! So that the people of Israel would repent and be washed from all their sins.
"The God of our ancestors raised Jesus from the dead after you killed him by hanging him on a cross. Then God put him in the place of honor at his right hand as Prince and Savior. He did this so the people of Israel would repent of their sins and be forgiven." Acts 5:30-31 nlt
