2 Timothy 2:3-7
"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.
And also if anyone competes in athletics, he is not crowned unless he competes according to the rules.
The hard-working farmer must be first to partake of the crops.
Consider what I say, and may the Lord give you understanding in all things."
