You've mentioned these concepts several times so I think it is time to address them:
Hi, thanks for sharing. I understand it differently. I believe they went to Paradise I believe: For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness (Romans 4:3). I believe OT saints like Adam, Abraham and David were all saved by believing in God as we are which when Jesus led the captives free and ascended to Heaven after the resurrection, he took them to Heaven.
1. The great universal church teaches that Eph 4:8 is a reference to LIMBUS PATRI--meaning the place of limbo occupied by the fathers (Old Testament fathers like Abraham, Moses, David, Samuel, Isaiah, etc.). Their idea asserts that these men were captives trapped in limbo before Christ "ascended" to heaven and made it possible for them to go there, too. In this way, Christ supposedly led "captivity (the fathers) captive" to Himself and took them to heaven. This whole concept is rather illogical when one thinks of righteous men trapped in captivity in some vague spiritual "neverland" or "prison" for thousands of years until Christ could "free" them.
The real meaning here is simply that those who serve sin are captive to it and are its servant or slave (Rom. 6:16-19), until they repent. Christ ascended to heaven, to become our High Priest (Heb. 4:14-16) and intercede for us, so we can receive forgiveness of sins and be offered salvation--and the gift of God"s Holy Spirit (Phil. 2:6; II Cor. 13:5). At conversion, Christians become captives of Christ (instead of sin) and servants (slaves) of righteousness.
Ephesians 4:8 is about conversion, not salvation. Romans 6:17-18 states, "But God be thanked, that you were the servants of sin, but you have obeyed from the heart
Being then made free from sin, you became the servants of righteousness." When this occurs, one is no longer captive to sin--and Satan (II Tim. 2:26)!!!
So, all who die in the Lord now go straight to Heaven, as Stephen said when he saw Heaven open up and prayed to Jesus asking him to receive his spirit,
2. Every human being has a spirit (spirit in man). But nowhere from Genesis to Revelation will you find this spirit with a life of its own outside the body.
and Paul said it was much better to be absent from the body and present with the Lord.
3. You must be referring to 2 cor 5:1-8. Read the verses carefully. It merely explains that Christians have two bodies: one physical (the first body), then a spirit body (at the resurrection). Paul was speaking of this spirit body, which comes later at the resurrection.
