The tomb is not necessary for the divine nature of Jesus. The divine nature of Jesus could have been raised immediately. The tomb is essential for the human nature of Jesus.
Love doesn’t run out or get used up. The Love of God and the Love of those we have lost to death multiply. It strengthens, and it intensifies every time we give it away.
God wants to light the fire in our belly that we cannot turn away from. He calls us into the light. When we fall in love with God, the fire of love explodes in our souls.
