6 If you put these things before the brothers, you will be a good servant of Christ Jesus, being trained in the words of the faith and of the good doctrine that you have followed. 7 Have nothing to do with irreverent, silly myths. Rather train yourself for godliness; 8 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. – 1 Timothy 4:6-8
The word training just seems to conjure up unpleasantness for me. Some people are more tolerant of long hours of training and hard work than others are. In sports, we tend to call them professionals. There is no shortcuts in life, whether it be in sports or in spirituality. Training is what we are called to do. Paul reminds us that physical training can be of some value. Losing weight and being in better shape is a good thing. But losing spiritual flab and being spiritually toned is far more valuable (and a lot less sweaty).
