Do you remember that we are told that when you are brought in front of some to give witness of your faith, no to worry because **the Holy Spirit will teach you **in that moment what to say. Therefore to memorize the Bible is like not believing in the Holy Spirit and its power. It is true that we should study to be able to teach and rebuke, but not always will be like that. When the Holy Spirit will dwell in all there will not be need to study any more, because he will give us light into everything even powers over nature to control it.
“I write this to you about those who would deceive you; but the anointing which you received from him abides in you, and you have no need that any one should teach you; as his anointing teaches you about everything, and is true, and is no lie, just as it has taught you, abide in him.” 1 Jn 2:26-28
"But the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and bring to your remembrance all that I have said to you."Jn 14:26
But why it is not like this now?
“And this is the judgment, that the light has come into the world, and men loved darkness rather than light,** because their deeds were evil. **” Jn 3:19
“If you love me, you will keep my commandments.
And if we keep His commandments then he will do something for us:
“And I will pray the Father, and he will give you another Counselor, to be with you for ever, the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him; you know him, for he dwells with you, and will be in you.” Jn 14:15-17
In the love of Christ who taught us the truth,
