Dear Greg & Doves,
Thank you for writing to me Greg. My orientation is Mid-Acts Dispensationalism, where "the beginning of our era" is not Acts 2 but rather at the time when Paul was saved. Paul was still a practicing Pharasee when the Holy Spirit fell on Pentecost, a Jewish feast day, so the Gospel of Grace was not yet revealed. Therefore, the Christian Church had not yet been born. Only the Gospel of the Kingdom was being preached at that time. Here are 2 links that go into more detail regarding Mid-Acts:
For your consideration, I listed your scripture verse citations below followed by link(s) to verse by verse sermons with sermon outlines from a Mid-Acts perspective.
All the Best,Mike P.
