I believe that the gifts of healing are operating today; but our focus must not be on the gifts..although when they come we are to receive them, thank God, and be grateful. We need to praise and worship God because God is God..The Giver is always more important than the gifts.
And caution is always good.. We need to see the "fruit of the spirit".. in the lives of those who minister gifts. See Galatians 5:22-23. (NIV) "But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control . "
1 John 1:4 (NIV) "Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world."
