I really believe in healing. I attribute this to the fact that the Bible really says God will heal us. A couple of months ago, I had the privelege to observe Terry Virgo laying hands on people and praying for healing. It was a memorable experience. One woman in particular I will always remember. He prayed for her and then asked if the pain was gone, to which she responded "no". So what do you think he did? Apologize and move on? Pretend the healing might "kick in" later? He kept praying, and praying harder until she joyfully shouted out "it's gone, the pain is gone!" and proceeded to have him pray for another problem she had and was also healed of that pain. I'm not trying to say that God never sovereignly ordains pain and sickness (in fact, he's completely in charge at all times), but how often do we fail to earnestly seek God's face to find his will about situations instead of sitting back and just letting "Fate" decide?
My Dad always said ( and he was no charismatic) that you shouldn't go to pray for the sick without knowing whether it was God's will to heal them or not. You should always be able to pray in faith, in the Spirit, praying the very heart of God over them. He has always testified that though he was not given the 'gift of healing', there were however specific times that God told him to pray for healing and in each case the person was healed. He taught me that you don't show up and pray "whatever your will Lord, do it" but you take the time to find out the Lord's will is, and then pray it! Of course there will be times when He hides his specific plan for us and others, but most of the time, I think He's calling us nearer through our not knowing, waiting to reveal his will at the right moment.
