You therefore, my son, be strong in the grace
that is in Christ Jesus. 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. You therefore must endure
hardship as a good soldier of Jesus Christ.
No one engaged in warfare entangles himself
with the affairs of this life, that he may please
him who enlisted him as a soldier.
--2 Tim. 2:1-4
