Where does Les Feldick go in the Bible to show how the resurrection of the Body of Christ comes about?

The teaching turns to 1 Corinthians chapter 15, verse 23, and also goes back into the book of Acts. This combination is used to show how the next order of the resurrection comes about, namely the resurrection of the Body of Christ.

Les Feldick says he is picking right up where the last program ended, at 1 Corinthians chapter 15 and verse 23. He notes, however, that they were going back into the book of Acts. The goal is to show how this next order of the resurrection comes about, which would be the Body of Christ. He also describes the setting as an informal Bible study.

1 Corinthians 15:23

But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming.

Why does Les go back into the book of Acts when teaching about the next order of the resurrection?

He returns to the book of Acts to demonstrate how the next order of resurrection comes about, namely the Body of Christ. The study resumes from 1 Corinthians 15:23 but traces the Acts account to show how that resurrection order is established.
