2nd Timothy 2:15 ESV
“Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth.”

Being able to know the scriptures in such a way as to distinguish what it is saying to you takes perpetual reading, understanding, application in our own lives. Reasoning what God would have us to do, intelligently discussing the scriptures with others and Listening when someone else has good understanding of how the word applies to us as a whole, that is being a proper student of the Word.
