I Timothy 4:8
Train yourself in godliness, for, while physical training is of some value, godliness is valuable in every way, holding promise for both the present life and the life to come.

Be reminded that physical training is of some value. It is important to take care of yourself, SO THAT you can continue God's work here on earth as it is in heaven. But we are also reminded of our priorities. Take care of yourself, with your physical body being important, but with your spiritual self being more important. Walk a mile every morning and read your Bible every night, but place the greater emphasis on your time with God.
