Was the church age ever mentioned in the prophetic time when God is dealing with Israel?
No. Throughout the prophetic time when God deals with Israel, the church age is never mentioned. The prophetic record is totally silent about the age of grace, with not a word about Him going to Gentiles to call out a people for His name. It remains unmentioned in all prophecy.
Les teaches that all through the prophetic time when God is dealing with Israel, the church age is something that is never mentioned. Not a word about the age of grace, nor about Him going to Gentiles to call out that multitude of people for His name; it is totally silent. He contrasts Israel's history, where God laid things out on a timetable—430 years from Abraham's call to Israel's exodus from Egypt, 490 years from one temple to the next, 490 years from Daniel's prophecy to Christ's appearance on Palm Sunday—with the age of grace, an undetermined period. In that church age there is not a single time element ever mentioned.
