Why is exercising godliness important for Christians?

In 1 Timothy 4:8, Paul contrasts physical exercise, which has temporary benefits, with godliness, which provides promise for both this life and the eternal life to come. Cultivating a life of piety is essential for Christians because it enables them to reflect Christ and grow in their relationship with Him. Furthermore, a life of godliness encourages mutual edification within the body of Christ. Believers are encouraged to pursue godliness intentionally, fostering spiritual growth and allowing them to be effective witnesses to the truth of the Gospel.
