kjv@1Thessalonians:4:1@ Furthermore then we beseech you, brethren, and exhort you by the Lord Jesus, that as ye have received of us how ye ought to walk and to please God, so ye would abound more and more.
It is clearly evident that this church is operating in a good amount of love. Paul exhorts them to love all the more and gives them a picture of what that is to look like working quietly and honestly with their own hands, abstaining from the prevalent idolatrous fornications and lusts.
There are differing theories that can be scripturally supported regarding the dead in Christ. The most common would suggests that this passage is speaking of the body being at sleep but the spirit being fully awake and present with the Lord. This would allow for Paul's 'being absent from this body means being present with the Lord' comment as well as Jesus' 'this day you will be with me in paradise' statement as well as others (beggar and rich man etc..). Others suggest this is a literal sleep (like Lazarus), that time is imperceivable in eternity, that from our side this sleep is for a while, from eternity it would be instantaneous. There are other plausible explanations as well. Either way, the Lord has matters well in hand, and the soul is at a state of grace and peace.
