This Sunday, we’ll begin a new sermon series on the book of Revelation that’ll take us into June. The series graphic combines numerous symbols from Revelation: Alpha and Omega; blood (of the slain lamb, martyrs, nations, etc.); 7 (churches, judgements, etc.); and seal, trumpet, and bowl.

Grant Osborne, Revelation
Richard Bauckham, The Theology of the Book of Revelation
Here are a couple summary videos for Revelation from The Bible Project:
