Why didn’t ‘the man Jesus’ stay dead?

On the first day of the week, Mary Magdala came to the tomb early in the morning, while it was still dark, and saw the stone removed from the tomb. So she ran and went to Simon Peter and to the other disciples whom Jesus loved, and told them, “They have taken Jesus from the tomb, and we don’t know where they put him.” So Peter and the other disciples went out and came to the tomb. Jn 20:1-3

On the cross, there came a point when Jesus’ heart stopped beating and his lungs stopped breathing. Why is it that he didn’t stay dead?
Because he was God. Well, we know that God doesn’t die. But what about his humanity? Why didn’t Jesus, as a man, die once and for all? Because God – life flowed through his humanity too. When God became flesh, it was a permanent union between the “God” and the “human”. That’s why Jesus, even in his humanity, could not stay dead. God – life ran through and through his humanity.
What about us?
Same thing: we have been given the gift of God – life, which runs through and through our humanity… which means that, as a human being, with a transformed human body, I can live forever.
Happy Easter
