Hi Daniel,
If you will read Luke 21:28, it plainly states that we are to "look up and lift up our heads" to see a visual event which precedes our redemption , ie. our resurrection/rapture. This is the visual sign for us to watch for that will tell us "our redemption draws neigh". The visual sign that we are told to watch for just before our rapture is described in the preceding Scriptures beginning with Luke 21:20-27. Luke 21:20-27 describes the Gog-Magog War perfectly if you read Ezekiel 38:16.
Watch for the sign ,
Your brother in Christ.
