What the Bible says about Glory of God to Conceal a Matter
(From Forerunner Commentary)
Exodus 4:11 underscores God's sovereignty over human physical and spiritual abilities. In responding to Moses' resistance to His summons to service, God declares that He is responsible for the organs that work and those that do not. Whatever speech difficulties Moses had were entirely in God's hands. Moses had claimed he was “slow of speech,” and if so, God counterclaims to be the source of that impediment and also the potential solution to it. Such a minor problem could not impede God's ability to work through him.
Likewise, whether one sees or is blind is in God's hands. Although God refers directly to physical capabilities here, His sovereignty certainly extends into spiritual ones as well. He governs humanity's ability to see (and hear) spiritually. As Solomon observes in Proverbs 25:2, “It is the glory of God to conceal a matter.”
