It's not the successful completion of a higher education that will guarantee a person will make a good leader, teacher, or servant of the Lord. I want to be taught the Bible by those who themselves have been well-taught the Bible and have also been given the gift of teaching.
I find it interesting how God chose Amos a caretaker of livestock and fig trees to be a prophet among his chosen people. [Amos 7:14b-15] I was a herdsman and a tender of sycamore-fig trees. But the Lord took me from following the flock and said to me, ‘Go, prophesy to My people Israel.’ Don't believe the lie that not having a certain level of education can limit or affect what God does through you or other individuals.
