Doing life together well and according to the ways of Christ involves messiness. The church can not be self-preservational. Still, we all need to be patient with each other. People experiencing disability, for example, deserve to be fully integrated in the life of our churches. Likewise, people facing challenges need to be patient with the persevering church. That kind of patience is a form of grace.
The Gospel answers hard questions and gives ultimate hope. The church has an enormous opportunity and responsibility to engage those questions, serve in love and wholeheartedly include people with disabilities in the life of the church family.
Paul describes the church using the metaphor of the human body. God arranged the members of the body as he chose. Some parts were weaker but indispensable and others less respectable but treated with special honor and greater respect.
(See 1 Corinthians 12:14-27.)
