Is there a logical flow in 2 Timothy 2:4-7?

> 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. *(2 Timothy 2:4-7, KJV)* These statements seem disconnected to me. Considering that Paul is asking Timothy to consider these things, I would think there is some connection between these counsels.
