I am a Christian counselor, working in this capacity for over 30 years, and even the people who are Christians don't understand that they sometimes need to see a doctor for a complete physical checkup. They think prayer will heal them, and want to avoid the need for more. What I pray for the most is discernment - for the wisdom to not go beyond my range of experience and knowledge.
It usually becomes evident that the person is not ready for spiritual counseling when they are not able to focus, or unable to easily grasp simple concepts from the bible that require an action on their part. And are not able to. And I ask them if they have seen a doctor. And encourage them to do so.
However, when this happens, I find that sometimes just sitting beside them, praying silently or very quietly seems to help them tremendously. Nothing is talked about. They are just ministered to - sometimes holding their hand - or touching their arm. Sometimes not. Often a peace comes over them as I'm praying. Some have come back saying that they felt this peace the whole week. They just want more!
Could this be a missing element in the body of Christians ministering to each other? This just being the presence of Christ to them?
