For if we believe that Jesus died and rose again, even so those who have fallen asleep in Jesus will God bring with him.

 4:1-8 Finally then, brothers, we ask and urge you in the Lord Jesus, that, as you have received instructions from us as to how you must behave to please God, even so you do behave, that you may go on from more to more. For you know what orders we gave you through the Lord Jesus; for this is God's will for you, that you should live consecrated lives, I mean, that you should keep yourselves from fornication, that each of you should know how to possess his own body in consecration and in honour, not in the passion of lustful desire, like the Gentiles who do not know God, that in this kind of thing you should not transgress against your brother or try to take advantage of him. For of all these things the Lord is the avenger, as we have already told you and testified to you. For God did not call us to impurity but to consecration. Therefore he who rejects this instruction does not reject a man, but rejects the God who gives his holy Spirit to us.
