And Jehovah said to him, Who has made man's mouth? Or who makes the
dumb, or the deaf, or the seeing, or the blind? Is it not I Jehovah?
Moses tells God that he didn't do the greatest job on his mouth. He says he is "heavy of mouth" and "heavy of tongue." Good description. However, in spite of his qualms, God doesn't relent. God responds with a kind of a rhetorical question put down. God knows Moses' mouth. The reply, however, is much broader when it says "who made man's mouth." To me the implication is that God knows about mouths (being the inventor) not just Moses' mouth, and also knows about the variations within and between mouths. "Who makes the dumb" God goes on to say, implying 1) that he knows of the variation between mouths, and 2) that he made the variations between mouths. That is, God even made the mouths of the dumb, those who cannot speak for whatever reason.
These observations on God's part are not restricted to the mouth, however. He goes on to say, "or the deaf" (i.e. variations in the ear) or the "seeing or the blind" (i.e. variations in the eye). Once again, the implication is that God created the variations we see in human beings, down to what are called disabilities; being unable to speak, unable to hear, or unable to see. One would assume that these variations could also include other types of "disability" including physical and mental differences. After all, sensorineural deafness and blindness imply nerve tissue insults or changes which would include mental retardation.
Taking this type of thinking to its final conclusion, these individuals we call persons with disability, are in reality part of the normal variation within human functioning. To think that God created a person who is unable to speak as a person who is unable to speak changes 1) the way I think about that person, 2) the language I choose to describe the abilities of that person, 3) the notion of who God is.
We will revisit these ideas.
