This message was impressed upon me, as I was in the middle of hearing a sermon regarding the church of Laodicea.....but this passage in regard to the church of Sardis, struck me profoundly. It was a very stark warning that I have seen before, but I had not studied in depth....it is a warning for believers. Rev. 3:2 Be watchful, and strengthen the things which remain, that are ready to die, for I have not found your works perfect before God. 3 Remember therefore how you have received and heard; hold fast and repent. Therefore if you will not watch, I will come upon you as a thief, and you will not know what hour I will come upon you. Rev. 16:15 "Behold, I am coming as a thief. Blessed is he who watches, and keeps his garments, lest he walk naked and they see his shame." Sounds familiar, right? Matthew 24:42 Watch therefore, for you do not know what hour a your Lord is coming. 43 But know this, that if the master of the house had known what hour the thief would come, he would have watched and not allowed his house to be broken into. 44 Therefore you also be ready, for the Son of Man is coming at an hour you do not expect. The message is given from Jesus, many times! Mark 13: 33 Take heed, watch and pray; for you do not know when the time is. 34 It is like a man going to a far country, who left his house and gave authority to his servants, and to each his work, and commanded the doorkeeper to watch. 35 Watch therefore, for you do not know when the master of the house is coming--in the evening, at midnight, at the crowing of the rooster, or in the morning-- 36 lest, coming suddenly, he find you sleeping. 37 And what I say to you, I say to all: Watch!" Why is Jesus so fervent about this? Notice the contrast........sleeping/watching. We know it’s not really about “sleeping”, what then? We can also see this message repeated in 1 Thess. 5: 1 But concerning the times and the seasons, brethren, you have no need that I should write to you. 2 For you yourselves know perfectly that the day of the Lord so comes as a thief in the night.
