Another outstanding book of brief daily readings by Timothy Keller is his God’s Wisdom for Navigating Life, brief commentaries on the wisdom God provides for us in His Word.
From it the reading for February 20 is:
“Every word of God is flawless; he is a shield to those who take refuge in him. Do not add to his words, or he will rebuke you and prove you a liar” (Proverbs 30:5-6).
“His Word. The beginning of all wisdom is the “fear of the Lord.” But how do we know if we are relating to the real God? The answer is there is no real knowing of God unless we know Him through His Word. Otherwise we are creating a God out of our imagination. Proverbs assumes the truth of Scripture, but here is a strong claim that God’s Word is flawless, that is, that it is perfect, sufficient, and without error. Of course Agur is thinking only of the prophecies and Scriptures that had been written up to his day. But there is a similar warning at the end of the entire Bible (Revelation 22:18-19) to not add to God’s Words.
“Taken together, Proverbs 30 verses 5 and 6 teach against two equal, opposite errors: either to think that some of God’s words are outdated, obsolete, untrue or to treat one’s own insights and “revelations” as equal to the scripture. Modern skeptics make the first mistake. Many Christians make the second mistake, lifting up their religious traditions, or their inner feelings, or their cultural preferences to the level of revelation, so they are equal with the Bible. We must do neither.
“Are you completely convinced of the full authority of the Bible—of every word? Are you committing either of the two main errors?
“Prayer: Lord, ‘I have more insight than all my teachers, for I meditate on your statutes’ (Psalm 119:99). I know some people with little formal education who through their knowledge of Scripture are wiser than worldly experts. Let Your Word light my path as well. Amen.”
