Okay, just to keep this discussion going because it is very interesting, here is my understanding... The OT saints were not sealed with the Holy Spirit because the Holy Spirit did not indwell people until Pentecost. The OT saints were kept in paradise until Jesus was resurrected and then they were released from paradise and rose with Him. The Holy Spirit "came upon and at times filled the old testament saints for a specific purpose of God but were not indwelt. Until Pentecost, the Holy Spirit resided in heaven. The promised Holy Spirit was not able to come until Jesus completed the work of redemption and went to heaven. There are many scriptures that support this and I can give them if you need them. I think we all agree they were regenerated in the same way by a work of the Spirit in their heart.
