This is the kind of observation that should cause churches and church leaders to pause. In America, nearly 20% of the population experiences some form of impairment. If you have this large a group of people (which is even larger when you consider the families of such folks) who might agree that disability ministry trumps other forms of ministry, you would think the desire to promote such ministry should move to be a significant priority.
Over the years, the pastors of my church have often told me of how often families who chose to attend Trinity Church came because of our desire to include people with disabilities or be in a church that includes persons with disabilities. Even folks of other religions, like Mormons, will at times send their family members to our church because of the opportunities presented there. People can be desperate for a place where their family member is included, loved and taught the things of the Lord. Unfortunately, that is something that is to often difficult for families to find. But when it is found, it is a truly beautiful thing!
