2 Timothy 2:2-5

2What you have heard from me in the presence of many witnesses, commit to faithful men who will be able to teach others also.

3Share in suffering as a good soldier of Christ Jesus.

4No one serving as a soldier gets entangled in the concerns of civilian life; he seeks to please the commanding officer.

5Also, if anyone competes as an athlete, he is not crowned unless he competes according to the rules.
