I appreciate that this is a weird question & kind of a backwards idea to knowing the Bible. Nonetheless, I think it’s a really significant thought & definitely worth your consideration. I say this because I grew up with heaps & heaps of Bible content: my mom started memorizing Proverbs when I was around 8years old, I went to Sunday School every week, took Bible classes in high school, etc. I would say that I have a relatively firm grasp on the Bible.
But I don’t think that having a sturdy grasp on the Bible is as important as the Bible having a firm grasp on us. I say this because we can far too easily quote the Bible instead of live it, or let the Bible live through us.
I think about this in terms of Paul’s words in Colossians 3:16, about the Word of God living richly in us. If I’m going to let the Bible know me, then I need to give the Bible access to my thoughts, emotions, secrets, dark corners, painful memories, relationships, character, priorities, etc. When the Bible lives richly in me, when the Bible knows me, then I find that I grow & mature in being Jesus’ follower. Let’s not only know the Bible, but let’s allow the Bible to fully know us!
