I don’t think we should have a legalistic drive to read Scripture (Yet, remember, a train is most free when it is where it should be; on the tracks). But Scripture is very very very important. Jesus said sanctify them in truth. Then He said, “Your Word is truth” (Jn. 17:17 cf. Ps. 119: 9, 11, 165 and beginning of Prov. 7 in context). God has also, significantly, chosen to reveal Himself through Scripture. God does do all sorts of stuff for us outside of Scripture (common grace, restraining grace, outside of countless other graces). He give us friends. He gives us beautiful “blood moons” to enjoy. And that should make us weep in appreciation. But that does not mean that we act like the man stranded on top of the roof in a flood who prayed for God to rescue him. In heaven he asked, “God why didn’t you rescue me?” God said, “I sent the Marines, I sent a helicopter, I sent…” God has revealed Himself! He has revealed Himself most pointedly in His Word. We should not neglect it.
I do think it is interesting to think that the majority of the writers of Scripture could not have had ready access to Scripture. Of course, the OT writers would not have known of the NT and likely had very little of the OT ready at their fingertips. Psalm 119 was composed about the OT, that’s kind of an obvious but wild thought.
Matthew, Mark, Luke, John, who wrote Scripture, didn’t themselves read Scripture every day; or, not likely. Paul also would not have likely read the Word every day (cf. 2 Tim. 4:13). Though, through his vast quotations of it, he clearly had hidden God’s Word in his heart.
So, no matter how we cut it, I don’t think we have to read Scripture every day. And, yes, I do believe in the Holy Spirit (though, sadly, not as I should). The Holy Spirit can and does speak to us. But, the Holy Spirit did already give us a book. And that book is supposed to be used to interpret what He says. So, it is very vital. Paul reminds us that Satan is tricky and parades himself around like an angel of light (2 Cor. 11:13-15; cf. 2 Thess. 2:9-12; Acts 17:11). We need God’s Word to interpret reality for us. We need God’s Word to interpret our emotions to us. His Word cuts deep (Heb. 4:12).
We don’t have to read the Word every day. But it is a huge privilege to be able to (Matt. 13:17)!
For me, recently, less has been more. I spent one day really just thinking hard on God’s restraining grace and it was powerful. I spent another day just thinking about the fact that we live coram deo, before the face of God. I think I would do well to feel less strained in my pursuit of God.
God does not love me more if I consume more of His Word. However. I do want to know Him more. Yet, that may mean less intake and more savoring.
