Week after week, Christians sit under the preaching of God’s word in worship. How do we know if the food we’re receiving is spiritually healthy? What will be its long-term effects on our soul-health? If I keep feeding on this teaching, will my spirit be better off for it, or will I look back someday and wish I’d made wiser choices?

Organic? Free-range? Many of us are learning to consider the long-term effects of what we’re eating. What consequences will the hormones pumped into the chickens and cows produce for me and my family over time? How harmless is it to consume a “genetically modified organism”?

Such questions, of course, can be overdone, but for many, these are sober-minded, diligent concerns. Especially when we’re not just choosing our own food, but sustenance for others, even our children. And if such bodily concerns can be of some value (1 Timothy 4:8), should we be any less careful about our spiritual diet?

Week after week, Christians sit under the preaching of God’s word in worship. How do we know if the food we’re receiving is spiritually healthy? What will be its long-term effects on our soul-health? If I keep feeding on this teaching, will my spirit be better off for it, or will I look back someday and wish I’d made wiser choices?

Determining Factor

More to the point, how will we know whether the full sweep of Christian content we’re regularly feeding on is healthy — not just weekly sermons, but daily devotionals, Christian books and podcasts, social feeds, and even real-life spiritual conversations? Aside from generally knowing the Scriptures better from cover to cover, which is a lifelong pursuit, how can we tell along the way that the places from which we’re feeding are nourishing?

Put another way, might there be any key indicator or determining factor for discerning whether Christian teaching or doctrine is healthy or not? Is there any litmus test, or organizing principle, or heart, or core, or touchstone, of what makes teaching “sound” or unsound? Healthy or unhealthy? Paul doesn’t provide a comprehensive plan, but he does give us something tangible to lean on in 1 Timothy 1:10–11.

Dividing Line

The phrase “sound doctrine” (literally “healthy teaching”) at the end of verse 10 is one of the most important concepts in 1 Timothy, as well as 2 Timothy and Titus (“the Pastoral Epistles”). Paul paints a stark contrast between good teaching and bad. Between healthy teaching and unhealthy. Between the kind of teaching that produces healthy spiritual lives (“godliness”) and the kind that does not. False teaching will produce spiritual sickness (1 Timothy 1:3; 6:3–4). True teaching will produce long-term spiritual health (2 Timothy 4:3–4; Titus 1:9; 2:1).

And what’s especially important about this first mention of “healthy teaching” in 1 Timothy 1:10 is that, more than anywhere else, it answers for us what is the key to “healthy teaching” or “sound doctrine.”
