A church-age reading widely taught in the dispensational stream, and of uncertain origin, sets the seven kingdom-parables of Matt 13 beside the seven letters of Rev 2–3: sower / Ephesus, tares / Smyrna, mustard seed / Pergamum, leaven / Thyatira, hidden treasure / Sardis, pearl / Philadelphia, dragnet / Laodicea. The mapping is often credited to C.I. Scofield, but his own notes on Matthew 13 make no such link: he reads the seven parables together as "the result of the presence of the Gospel in the world during the present age"
(Scofield Reference Bible, PD), and never sets them beside Revelation 2–3. Chuck Missler is the teacher this page can actually cite for the parallel; he develops it in his verse-by-verse Revelation commentary (cite-only, ≤50 words): the parables and letters together sketch one continuous portrait of the church age, sower to dragnet, first love to lukewarm: the kingdom's mixed field maturing exactly as the churches do.
