When a new bodybuilding contraption is introduced, it is always demonstrated with well-muscled people who claim the particular device helped them build that awesome 6-pack! But that's a lie! Those pumped-up bodies is the result of years of dedicated physical training.
Apostle Paul is not impressed. He says: "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." (1 Tim.4:8) So why not practice "godliness" and instead build 6-packs abs for God?
