Behold My hands and My feet, that it is I Myself. Handle Me and see, for a spirit does not have flesh and bones as you see I have." When He had said this, He showed them His hands and His feet. But while they still did not believe for joy, and marveled, He said to them, "Have you any food here?”
Luke 24:39-41

When the disciples were wrestling with their doubts and fears about Jesus’ resurrection, He appeared to them and told them, “Behold My hands and My feet, that it is I Myself. Handle Me and see, for a spirit does not have flesh and bones as you see I have," followed by this request: "Have you any food here?”

This gives us some idea about what Jesus’ resurrected body looked like.

It was a physical body. The Lord did not merely rise spiritually as a sort of phantom. He rose bodily.

His resurrected body bore the scars of His crucifixion. This validated who He was and what He had suffered on the cross. Assuming His body in the New Heavens and the New Earth retain the scars (and I believe it will**), we will behold our Savior for eternity, remembering the price He paid to save us—not to make us feel bad, but to prompt and prolong our eternal worship and praise.

His resurrected body ate food, not only here (Luke 24:41 & 43), but maybe also by eating fish on the beach with the disciples (John 21). Jesus’ physical, resurrected body ate, and so we may surmise that we will too. This is just one more indicator that glorified bodies, though in someway “glorified,” are physical. Beyond this I will refrain from speculating.

**The chief reason I believe Jesus’ body in Heaven will retain the scars of His crucifixion is that in several places in Revelation (5:9; 5:12; & 13:8), Jesus is seen as both “the Lion” and “the Lamb that was slain.” This seems to indicate rather forcefully that in Heaven we will somehow see Jesus as both the conquering and ruling Lion, and the Lamb that was slain—complete with the scars.
