What does 2 Timothy 4: 7: 18 mean?

Brothers and sisters, we have just read 1 Timothy 4: 7-8. This verse is a letter written by the apostle Paul to Timothy, telling us that it is not good to exercise. If you practice godliness, everything will be fine. Now that our living conditions are good, everyone pays attention to health. However, mental health is more important than physical health, because we are all tourists in this world and children of God, so the growth of spiritual life is very important.
