He doesn't think someone is more qualified because they have all sorts of letters behind their name. He looks at the heart and what you have hidden there.
He's not against education of course, but it isn't necessary for everyone.
And some degrees are necessary because we sure don't want surgeons being self-taught or bridge building engineers to eyeball their project and just wing it!
God can and will use anyone He chooses to get His message out in the world.
Is He asking you to go?
Is He asking you to speak up?
Is He asking you to preach the Word?
Amos knew all about this. The king called him a prophet (because Amos was prophesying), but Amos denied it. He said, "I am not a prophet, nor am I the son of a prophet; for I am a herdsman and a grower of sycamore figs. But the LORD took me . . . and said to me, 'Go prophesy to My people'" Amos 7:14-15
Sometimes we put limits on ourselves or others. We might think he can't do that. He's not qualified. He doesn't have a theology degree. She can't do that. She isn't a preacher.
God doesn't believe in these limits. He doesn't even acknowledge them. He calls who He calls.
Ask the original disciples. Pete was a fisherman. Matt was a tax collector. None of them were priests.
"but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence;" 1 Peter 3:15
