2 Timothy 2:2-5

2And the things that you have heard me say among many witnesses, entrust these to faithful men who will be qualified to teach others as well.

3Join me in suffering, like a good soldier of Christ Jesus. 4A soldier refrains from entangling himself in civilian affairs, in order to please the one who enlisted him. 5Likewise, a competitor does not receive the crown unless he competes according to the rules.
