2 Timothy 2:5

3 Thou therefore endure hardness, as a good soldier of Jesus Christ.

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.

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.

Do read the surrounding verses too, because the context often says more than a single verse.
