For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come.
I Timothy 4:8 NIV
There is value in physical training. It makes you stronger and tougher. Godliness works the same way. It makes you stronger and tougher spiritually.
The physical toughness helps in many ways, the spiritually training gives you an edge in all things. It will last right on through life. These aren’t either or. You can do both– physical training and growing in godliness.
