A wheel chair lifts up a person who otherwise has been lying or crawling. Now Rose, Michel, Issa, Mary, and Michael, for example, can look you in the eye, instead of being looked down upon.
It is a good thing to be lifted up in that way. But that is not enough. We pray that the people we met in Cameroon will trust in Jesus, our Savior and the son of God who "sets on high those who are lowly, and those who mourn are lifted to safety" (Job 5:11).
