Also once you have Christ living inside of you, you have the ability to ask for healing and miracles for yourself in you life. The people who have the gift I believe are place to heal the lost(both physically and spiritually) and bring them to Christ but those who have Christ already have healing by faith.
"He himself bore our sins in his body on the tree, so that we might die to sins and live for righteousness; by his wounds you have been healed." 1peter 2:25
"Then Peter, filled with the Holy Spirit, said to them: "Rulers and elders of the people! If we are being called to account today for an act of kindness shown to a cripple and are asked how he was healed, then know this, you and all the people of Israel: It is by the name of Jesus Christ of Nazareth, whom you crucified but whom God raised from the dead, that this man stands before you healed. Acts 4:8-10
