By the way....When the disciples on the mount of Olives asked the Lord about His coming and the end of the age they knew nothing of the church age, it was still a mystery to be revealed as we read in Eph.3:5.
So this would be revealed after the Holy Spirit was given and the church was officially started. We are still living in the Church age....The Tribulation will bring inescapable disasters and will escalate in intensity throughout the seven-year Tribulation period.
Hear here!~
