Since we are ALL sinners -
Romans 5:12;
Romans 3:23 - and death is the price tag that sin pays -
Romans 6:23;
Romans 6:7 -
then in order to enter heaven one would have to have a resurrection from the dead.
Even if you do Not agree, at least I hope you will see there are reasons why I think 1st Thessalonians is talking about resurrection.
What the 'slave' of the witnesses don't want it's members to know is, here is the resurrection of people that are still "alive".
Colossians 2:9-14 (ESV Strong's) 9 For in him the whole fullness of deity dwells bodily, 10 and you have been filled in him, who is the head of all rule and authority. 11 In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, 12
having been buried with him in baptism,
in which you were also raised with him through faith in the powerful working of God, who raised him from the dead. 13 And you,
who were dead in your trespasses and the uncircumcision of your flesh,
God made alive together with him, having forgiven us all our trespasses, 14 by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross.
Isn't this a resurrection?
Romans 6:1-4 (ESV Strong's) 1 What shall we say then? Are we to continue in sin that grace may abound? 2 By no means! How can we who died to sin still live in it? 3 Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? 4
We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too
might walk in newness of life.
Or this,
Romans 6:5-11 (ESV Strong's) 5
For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his. 6 We know that our old self was crucified with him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin. 7 For one who has died has been set free from sin. 8
Now if we have died with Christ, we believe that we
will also live with him. 9 We know that Christ, being raised from the dead, will never die again; death no longer has dominion over him. 10 For the death he died he died to sin, once for all, but the life he lives he lives to God. 11
So you also must consider yourselves dead to sin and alive to God in Christ Jesus.
