There are likely many genuine students of the Bible who know very little because they don't know Jesus. Knowing the Bible well, is not equal to knowing Jesus:
"Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity." Matt 7:22-23
Also many genuine students of the Bible who know much are nothing because they do not have charity/love:
"Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal.
And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.
And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing." I Cor 13:1-3
