2 Timothy 2:4-7 King James Version (KJV)
4 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.
5 And if a man also strive for masteries, yet is he not crowned, except he strive lawfully.
6 The husbandman that laboureth must be first partaker of the fruits.
7 Consider what I say; and the Lord give thee understanding in all things.
