“All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness…” -2 Timothy 3:16
To say that scripture is “profitable” has nothing to do with money. It simply means that scripture is useful, beneficial, or advantageous toward a certain end. In this case, Paul says that scripture is beneficial for four things: teaching, reproof, correction, and training in righteousness. John Stott suggests that these four are divided into two groups: creed and conduct.
Paul now goes on to show that the profit of Scripture relates to both creed and conduct (16b, 17). The false teachers divorced them; we must marry them. The NEB expresses the matter clearly. As for our creed, Scripture is profitable ‘for teaching the truth and refuting error’. As for our conduct, it is profitable ‘for reformation of manners and discipline in right living’. In each pair the negative and positive counterparts are combined. Do we hope, either in our own lives or in our teaching ministry, to overcome error and grow in truth, to overcome evil and grow in holiness? Then it is to Scripture that we must primarily turn, for Scripture is ‘profitable’ for these things.

Yes, marry them indeed. Every day. Every moment.
