1 Timothy 4:7-8 ESV
Have nothing to do with irreverent, silly myths. Rather train yourself for godliness;
For while bodily training is of some value, godliness is of value in every way, as it holds promise for the present life and also for the life to come.
Growth Is Not the Goal
The repeated focus in our spiritual exercises must be on Jesus, and not our effort. He is the greatest grace on these paths, not our own improvement.
