Lazarus was already dead for four days when Jesus arrived in Bethany.

He had been dead long enough for his body to begin decaying.

Now Jesus is here. What will he do? Lazarus has been dead so long that any thought of an immediate resurrection is out of the question. But that doesn't seem to be on Martha's mind. She thought Jesus could heal Lazarus, and she also believed he would be raised on the last day. It apparently never occurred to her that Jesus could raise Lazarus right then and there.

Jesus wept.
He ordered the stone removed from the entrance of the tomb.
He declared that this would be for the glory of God.
He called in a loud voice, "Lazarus, come forth!"

Someone has commented that if Jesus had not said the name Lazarus, every dead person in the world would have been raised. Certainly the raising of this one man proves Jesus can raise every person.

Death has no power over him, but he has absolute power over death.

There's an old gospel song called 'Since Jesus Came into My Heart'.
One of the verses contains this phrase,

"There's a light in the valley of death now for me, since Jesus came into my heart."

That light is Jesus.

If you know him, you need not fear death. To borrow a phrase from John Stott, death has become a "trivial episode" for the believer. It doesn't seem trivial to us at the moment, but Jesus has taken the sting from death. One day we will live in a land where death no longer reigns.
