Fun fact an easy way to remember how to spell Necessary is: Never Eat Cheese Eat Salad Sandwiches And Remain Young. Necessity is only changing the last three letters.
In this chapter we’re continuing our study of the four characteristics of scripture. We’ve already covered Authority (& Inerancy), Clarity and now [Never eat…]cessity.
The Necessity of Scripture means that the Bible is necessary for knowing the gospel, for maintaining spiritual life and for knowing God’s will, BUT it is not necessary for knowing something about God’s character.
Notice how this definition gives us three things we need the Scripture for, and one thing we don’t.
Necessary for Knowledge of the Gospel – This is mostly justified from Romans 10:13-17. Which reasons that in order to be saved we need to call on the Lord’s name, but in order to do that we need to believe in Him. In order to believe in Him, we need to hear about Him.
In this way one must read the gospel or hear it told to them in order to be saved. I have written about this elsewhere, in: “what about Jesus-dreams”. Where I wrestled with this Doctrine, on the basis of the stories I’d heard where people have had dreams/visions about Jesus and become Christians without the Bible.
Necessary for Maintaining Spiritual Life – Again, this is mostly justified by Matthew 4:4 where Jesus quotes from Deuteronomy “Man shall not live on bread alone”. But I guess we could also use 2 Timothy 3:16, where is says that all Scripture is useful for teaching, rebuking, correcting and training in righteousness.
Necessary for certain knowledge of God’s will – We may have some knowledge of God’s will without it, but certain knowledge is different. Even if we could conceive a way for God’s justice and mercy to be reconciled, we wouldn’t have enough certainty on it for it to save us.
He has not revealed everything in the scriptures, obviously there is no knowledge of nuclear physics etc, but we do have enough that we may know His will (Deuteronomy 29:29).
From a philosophical point of view, the Bible is necessary for certain knowledge about anything. Because either we know everything (which we don’t). Or we have the words of Someone who knows everything and who never lies.
The Bible is NOT necessary for knowing that God exists (or some of His attributes) – The Bible tells us that the heaven’s declare His glory (Psalm 19:1), that rain and fruitful seasons are signs of God’s blessing (Acts 14:16-17) and that God’s invisible qualities have been made known to all so that no one is without excuse (Romans 1:19-21).
Wayne Grudem makes a distinction between “general revelation” and “specific revelation”. Whereas general revelation is available to all as a result of God’s general grace to all people, specific revelation is what God has specifically made know through the Scriptures. (see notes below for more detail).
The Bible is NOT not necessary for knowing something of God’s character or moral laws – Therefore we are still guilty of sin even if we never hear the gospel (Romans 1:32, 2:14-15). The law has been written on our hearts.
This doctrine should make us inspired and challenged to proclaim the gospel as Romans 10 reminds us: How can they call on One they have not heard about, and how can they hear unless someone tells them!”
