TheWordIsOne
It is not up to you to judge the level of knowledge in a person as everyone are on different levels of learning as no one could ever exhaust the teachings that are contained in the word of God. Also, there are no mysteries in the word of God if you are allowing the Holy Spirit teach you and reveal to you what God wants us to learn.
Hosea 4:6 My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children.
Hosea 4:7 As they were increased, so they sinned against me: therefore will I change their glory into shame.
