Why did Jesus rise from the dead? To conquer death
I am the first and the last, and the living one. I died, and behold I am alive forevermore, and I have the keys of Death and Hades. -- Revelation 1:17b-18
On the cross, Jesus suffered for our sin and removed the claim that death had over us - for "the wages of sin is death" (Rom 6:23). But in his bodily resurrection, he destroyed the power of death. He took away the keys: Jesus owned death.
