Before we can answer this question, we need to understand the doctrine of the hypostatic union. It is the teaching that within the single person of Christ are two distinct natures: divine and human. This means that Jesus is both God and man. So when we see Jesus, we’re looking at the man, but within Him is also the divine nature. However, we cannot see divinity. It does not have a weight, shape, or color. We must perceive the divine nature through the human nature of Christ. Therefore, we would see Jesus, the man, literally walking and eating. This clearly displays His human nature. But we also see that He said that He would always be with us wherever we were (Matthew 28:19-20). This shows His divine nature.

When it comes to Jesus’ death on the cross, we must understand that it was not the divine nature of Christ that died. Instead, it was human nature. The divine nature is eternal and cannot die (Psalm 90:2; Malachi 3:6), but human nature can die, and Jesus did so on the cross.

So, when we say that Jesus is eternal, we are speaking of the divine aspect–that divine nature He possesses. But when we say that Jesus died, we are speaking of the human aspect–the human nature that died on the cross.

Jesus has two natures
