On Building Spiritual Muscle, Part 6

By DOlinger on Mon, 01/12/26

Read the series.

We’ve discovered three different spiritual exercises that will help us build spiritual muscle, thereby gaining spiritual strength so that we can be what we’re supposed to be, so that we can do what we’re supposed to do—to fulfill our part of this joint effort between us and God to conform us, over time, to the image of Christ (2Co 3.18). (Notice, by the way, that the “being” comes before the “doing.” That’s how it works; that how it has to work. Maybe that’s worth a blog post all by itself.)

We’ve looked at two of the exercise machines that build spiritual muscle. There’s one more.

On Building Spiritual Muscle, Part 4

Read the series.

You’ve had a few days on the first exercise machine—the Scripture—and if you’ve been diligent, you may have some sore muscles, ones you haven’t exercised in a while. Good for you.

What’s the next exercise machine?

Recall that we’re finding New Testament uses of the word grace where the context indicates that the word is speaking of spiritual strength, and where there’s some sort of practice indicated that builds up the grace.

Our second passage is probably familiar to you; it’s commonly included in Bible memory programs.

So welcome to the gym. You’ll notice the mirrors on the walls (Jam 1.22-25), as well as several exercise machines scattered around the room. Let’s talk a little about what they are and how they work.

On Building Spiritual Muscle, Part 2

Read Part 1.

I’ve suggested that our lives ought to be oriented around the work God is doing in his people to make them—us—more like his Son. I’ve also suggested that this work can be compared to an exercise program.

Although I think the analogy is helpful, I also recognize that it isn’t really useful unless the Scripture gives us reason to think that the sanctification process is in some ways similar to physical exercise.

Is there any evidence of that? Is there a biblical word for spiritual strength? And are there “exercises” attached to it?

What’s the most important question in the world?

I think my fellow Christians would agree with me that it’s the question of where you’re going to spend eternity. If there’s life after death, and if that life is eternal, and if there are different possibilities for the nature of that life, then it’s hard to imagine any question more important than that one.

Life and death. Heaven and hell. It doesn’t get any more consequential than that.

As the Philippian jailer put it so clearly and succinctly all those years ago, “What must I do to be saved?” (Ac 16.30).
