My friend JR Woodward recently posted A Theology of Healing on his blog. It’s a great introduction to the biblical teaching on sickness, healing, prayer and faith.
These are often uncomfortable issues for us to deal with as disciples of Jesus. Some who have seen healing prayer done badly find it easier to avoid the issue altogether than engage it thoughtfully, prayerfully, and biblically. Others who have had good experiences of healing prayer sometimes find it easier to disregard as “religious” those who have hesitations and questions instead of engaging patiently and humbly with the questions.
