Based on Acts 4:22 and the perfect being Jesus Christ, healing ministry is not dead. The point is not to be afraid but ask to ask.
All a believer has to do is pray and ask for the miracle of healing. Jesus says to aks and you shall recieve. The Lord says it is done. 1 Kings .
"But we have this treasure in earthen vessels, that the excellancy of the power may be of God, and not us." 2 Cor 4:7 KJV
