2 Timothy 2:4-7, 11-13

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

The saying is trustworthy, for: If we have died with him, we will also live with him; if we endure, we will also reign with him; if we deny him, he also will deny us; if we are faithless, he remains faithful
