2 Timothy 2:3-7

3 Share in suffering as a good soldier of Christ Jesus. 4 No soldier gets entangled in civilian pursuits, since his aim is to please the one who enlisted him. 5 An athlete is not crowned unless he competes according to the rules. 6 It is the hard-working farmer who ought to have the first share of the crops. 7 Think over what I say, for the Lord will give you understanding in everything.
