2 Timothy 2:4-7, 11-13

No man that warreth entangleth himself with the affairs of this life; that he may please him who hath chosen him to be a soldier. And if a man also strive for masteries, yet is he not crowned, except he strive lawfully. The husbandman that laboureth must be first partaker of the fruits. Consider what I say; and the Lord give thee understanding in all things.

It is a faithful saying: For if we be dead with him, we shall also live with him: if we suffer, we shall also reign with him: if we deny him, he also will deny us: if we believe not, yet he abideth faithful: he cannot deny himself.
