Our home is a bit older (built in the 70's) and has a few quirks, including one particular pipe that will freeze if the temps stay below -10 for a few days. My wife was very upset about this and wanted to do a big insulation project to fix it; but I told her that the fix was a lot easier than that; we just drip the sinks. Somehow just having a tiny amount of water going through the line keeps the pipes from freezing and allows us to avoid damage or the dread of no hot water on a cold day. The key is movement, as long as that water is moving it won't freeze.
Movement matters in faith too. Looking back on my life of faith, there have been times when my faith grew a lot in a short time; and other times where it seems it was almost stagnant...but no matter what, I've worked to keep moving forward, even if it was only a step at a time.
If we stop moving, it's easy to become complacent and allow apathy to set in and eventually we find ourselves stuck (or frozen) in place.
Philippians 3:13-15 says "Brothers and sisters, I do not consider myself to have taken hold of it. But one thing I do; Forgetting what is behind and straining toward what is ahead, I press on toward the goal"
So don't get stuck, keep on moving toward Christ.
