If the law of God, which is the least favorite part of God's Word for many, is so profitable, how much more delightful and beneficial must be the rest of God's Word? How about this description of the blessed man in Ps. 1? Because "his delight is in the law of the LORD, and on his law he meditates day and night," he is like "a tree planted by streams of water that yields its fruit in its season, and its leaf does not wither…" (Ps. 1:2-3). If so, can we be satisfied with the most basic, minimal amount of the knowledge of God's Word?
Add to this what the Bible is about. It is ultimately God's self-revelation. That means, if we approach the biblical knowledge properly, the more we know about the Bible, the more we come to know God--who He is, what He has done, and what He will do because He loves us so much. So, what would you say--is it the case that the more we know God, the better it is? It's hard to imagine anything more profitable than knowing God in a saving manner as our heavenly Father. But God is abounding in His goodness. He offers us not only the privilege to know Him but also the blessing of becoming like Him. Maybe I can explain it like this. Imagine someone you really respect and adore extending his friendship to you. That would be an amazing privilege. Can anything be better than that? Yes, if he is willing to spend time with you and help you to share in all the qualities that you admire about him! This, so you don't have to just admire him from distance while he does his thing; you can stand with him on the stage, for example, and sing with him! How amazing that would be! That's what the Bible is for.
