Do Christians really believe and act as if we have everything we need in Jesus Christ and His Word? Or for us is that just kind-of-sort-of true, in theory, while in practice we opt for additives to our Savior, some shiny therapeutic psychology, pragmatic church-building plan, or new-and-improved method in chalk for playing better zone defense against demons?

Last week my friend Amy Timco finished reading and wrote a review of John MacArthur’s 1999 treatment of this Biblical truth: Our Sufficiency in Christ. The full review is at YeHaveHeard, and here is a sample:

Many in the church don’t really believe that Christ has already granted us everything we need to live godly lives, turning instead to psychiatric medication and secular counseling. Some believe that the Bible is fallible and should be “updated” for our times, thus denying that God has given us all we need in its pages. Others contravene Christ’s sufficiency by studying techniques for spiritual warfare; they are convinced that unless they have a strategy in place, “Satan will have them for breakfast” (214), and Christ’s power alone is not enough to combat demons. What all these errors share is a basic disbelief in Christ’s perfect sufficiency.

As I slowly worked my way through this book, I was amazed at how often I unconsciously assume that what God has provided is not enough. “Oh, well, God’s provision doesn’t really cover THIS area” or “God is more concerned about this over here; He’s not really involved in that problem over there.” MacArthur doesn’t mince words and I appreciate his firmly biblical perspective on the issue. [… T]he sufficiency of Christ and His Word is something many Christians would agree with, but don’t really define clearly enough to work it out practically in our everyday lives. We scrape by somehow, but futility is a hallmark of our lives. And yet we possess such riches in Christ!
