Finally then, brothers, we beg and exhort you in the Lord Jesus, that as you received from us how you ought to walk and to please God, that you abound more and more.

 Paul lays down a great principle. The man who has lived and died in Christ is still in Christ even in death and will rise in him. Between Christ and the man who loves him there is a relationship which nothing can break, a relationship which overpasses death. Because Christ died and rose again, so the man who is one with Christ will rise again.
