I am convinced that God does not discriminate against the simple by making the scripture hard to understand. When the Spirit assists with understanding revelation flows regardless of our mental capacity.
If we need a PhD. to follow a scriptural argument then something is wrong.
In many cases the intellectual folk have a harder time receiving from Him as they are more likely to struggle with the challenge intellectual humility.
For this reason I studied the Scripture constantly for more than 5 years without any reference to other books or teaching. I knew that His revelation knowledge was a jewel to be sought above all else.
