How Can I Gain Understanding?

Q. It appears to me that there will always be things pertaining to GOD that
I will not know/understand regardless of the amount of study/prayer that I
engage in. What is a believer to do in these instances when what is/has been
revealed does not answer the questions that I have?

A. The first is to believe that God wants you to understand, and the second is pray for wisdom.

If any of you lacks wisdom, he should ask God, who gives generously to all without finding fault, and it will be given to him. But when he asks, he must believe and not doubt, because he who doubts is like a wave of the sea, blown and tossed by the wind. (James 1:5-6)
