God uses different ways to work His miracles in our lives
Dr. Roberto Miranda(Audio: Spanish)
When Elisha arrives at the Shunammite's house, the boy is still dead because Gehazi has not been able to perform the miracle, confirming what this woman suspected, that the prophet's own presence was required to perform the miracle.
So in verses 32 onwards we are shown Elisha entering and performing a series of, say, symbolic prophetic exercises to perform the miracle. It says that Elisha closed the door and prayed to the Lord, and then he got on and stretched out on the child, this is very curious because it tells us something about prophetic acts and symbols that many times as symbolically suggest and express what is you have to give in the spirit world.
