Will church age saints be resurrected together with Old Testament saints?
No. According to 1 Corinthians 15:23, every person is resurrected within their own company or order. Church age saints are not resurrected together with Old Testament saints. The firstfruits resurrection already occurred, and church saints are not part of it. They are separate companies.
Les explains that Christ was the first to be resurrected, and then Jewish saints were resurrected right after Him, comprising the firstfruits. This firstfruits is a plural concept, like the Old Testament feast where many stems of grain were brought together in a sheath to the priest. Les teaches that every man is resurrected in his own company, so church age saints are not resurrected with Old Testament saints. The church is not part of the firstfruits, because that already happened. He illustrates the harvest process: first the firstfruits were taken as a sampling, then the main harvest was gathered, and finally the gleanings were harvested last. This shows distinct resurrections in order.
But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming.
