Training your body helps you in some ways. But devotion to God helps you in every way. It brings you blessings in this life and in the future life too. Here is a true statement that should be accepted without question:
We hope in the living God, the Savior of all people. In particular, he is the Savior of all those who believe in him. This is why we work and struggle. Command and teach these things. You are young, but don't let anyone treat you as if you are not important.
Be an example to show the believers how they should live. Show them by what you say, by the way you live, by your love, by your faith, and by your pure life. Continue to read the Scriptures to the people, encourage them, and teach them. Do this until I come.
