When we say Scripture is sufficient, we mean that it is enough. But, enough for what? Scripture is enough for living a holy life. Scripture is enough for salvation.
Kevin DeYoung tells us in his book Taking God at His Word,
“God has given us all we need for life and godliness; Scripture is enough to make us wise for salvation and holy unto the Lord. If we learn to read the Bible down (into our hearts), across (the plot line of Scripture), out (to the end of the story), and up (to the glory of God in the face of Christ), we still find that every bit of the Bible is profitable for us. To affirm the sufficiency of Scripture is not to suggest that the Bible tells us everything we want to know about everything, but it does tell us everything we
need to know what matters most. Scripture does not give exhaustive information on every subject, but in every subject on which it speaks, it says only what is true. And in its truth we have enough knowledge to turn from sin, find a Savior, make good decisions, please God, and get to the root of our deepest problems.”
The Bible’s sufficiency is an encouragement to us to search the Bible for answers to life’s most important questions (II Tim 3:16-17). The Bible’s sufficiency warns us not to add to Scripture or to consider something of equal value to the Scripture. The Bible’s sufficiency keeps us from adding more sin or more requirements to those named in Scripture (Prov 30:6; Rev 22:19).
Do you live as if the Bible is enough for you? Who or what have you allowed to influence you or trump the voice that Scripture ought to have?
