2 Timothy 2:3-10

Thou therefore endure hardness, as a good soldier of Jesus Christ. 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. Remember that Jesus Christ of the seed of David was raised from the dead according to my gospel: wherein I suffer trouble, as an evil doer, even unto bonds; but the word of God is not bound. Therefore I endure all things for the elect's sakes, that they may also obtain the salvation which is in Christ Jesus with eternal glory.
