We are all self taught more than you might think.
Some have no choice but to study for their very survival and God allows it because He knows that by His Spirit He can lead them on their journey in truth and not the watered down version that is handed out so often in church.
Some, have learned to love the word because it is the light on their path....the means of keeping their feet in the right direction and not be sidetracked by all the false prophets, teachers, workers of miracles, self-agrandising liars that always seem to gather itching ears to themselves and various and sundry other things that distract from what is true.
And of course since God knows each of us better than we know ourselves, there are many ways He encourages because Jesus is the Good Shepherd and God sent Him to us and continues to point to Him as the One who is the way, the Truth and the LIfe.
A person not led of the Holy Spirit has the definite and distinct attribute of turning hearts to stone. Without the Holy Spirit, even the Bible becomes just more words.
63The Spirit gives life; the flesh profits nothing. The words I have spoken to you are spirit and they are life.
64However, there are some of you who do not believe.” John 6
