2 Timothy 2:1-4

Thou therefore, my child, be strengthened in the grace that is in Christ Jesus. And the things which thou hast heard from me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also. Suffer hardship with me, as a good soldier of Christ Jesus. No soldier on service entangleth himself in the affairs of this life; that he may please him who enrolled him as a soldier.
