Elisha had a great gift of prophecy, as well as a great gift of performing miracles. This was demonstrated in 2 Kings 3-9, although I'm sure these were not a complete list of all the things he did.

Many people have a hard time accepting Elisha's miracles as just that: miraculous. They try to "spin" them into being natural occurrences that ignorant people of that time simply misconstrued as being miraculous. Personally, I have no problem at all accepting Elisha's (and Elijah's) miracles as acts of God, using these two men as "tools" to perform the supernatural.

Before Elijah had been taken up into heaven, Elisha had asked to inherit a double-portion of Elijah's spirit (2 Kings 2:9). It appears that this request was granted to him by God.
