The Bible recognizes physical activity as having limited value for the present life, while emphasizing that godliness is of eternal significance. Christians are called to steward their bodies as temples of the Holy Spirit, engaging in all things—including fitness—with self-control and the ultimate aim of glorifying God.
While our culture often elevates the physical to an idol, Scripture provides a balanced view. The Apostle Paul teaches that while bodily exercise has its place, it is of limited value compared to the pursuit of godliness, which holds promise for both this life and the life to come. Furthermore, we are reminded that our bodies are not our own; they have been bought with a price. Therefore, whether we are exercising or resting, our ultimate goal is to glorify God with our bodies as temples of the Holy Spirit. As noted in 1 Corinthians 6:19-20, we are not our own, but have been purchased to honor Him. Similarly, 1 Timothy 4:8 confirms the limited but existing value of physical training compared to the supreme importance of spiritual discipline.
In the Reformed tradition, our physical health is a matter of stewardship rather than vanity. Just as an athlete practices self-control to win a prize, the believer exercises discipline in all areas of life, including diet, sleep, and physical exertion, to remain fit for the work of the Kingdom. The Westminster Larger Catechism Q.135 highlights that a 'sober use' of meat, drink, labor, and recreations is a duty required for the preservation of life. We are to run our race with purpose and clarity, not 'beating the air,' as Paul describes in 1 Corinthians 9:25-27, ensuring that we are not mastered by anything, even our own physical desires.
