2 Timothy 2:2-5 NIV
And the things you have heard me say in the presence of many witnesses entrust to reliable people who will also be qualified to teach others. Join with me in suffering, like a good soldier of Christ Jesus. No one serving as a soldier gets entangled in civilian affairs, but rather tries to please his commanding officer. Similarly, anyone who competes as an athlete does not receive the victor’s crown except by competing according to the rules.
NIV: New International Version
