2 Timothy 2:1-4
You therefore, my son, be strong in the grace that is in Christ Jesus. 2 And the things that you have heard from me among many witnesses, commit these to faithful men who will be able to teach others also. 3 You therefore must endure[a] hardship as a good soldier of Jesus Christ. 4 No one engaged in warfare entangles himself with the affairs of this life, that he may please him who enlisted him as a soldier.
