Q. Revelation 3:3 states “So remember what you have received and heard; and keep it, and repent. Therefore if you do not wake up, I will come like a thief, and you will not know at what hour I will come to you.” Does this verse imply for those that are awake that they will know the hour of his return? If so, it seems to contradict Mathew 24:36 “But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father alone.” Could you explain?
A. The Bible, being the word of God, cannot contradict itself, no matter who the various passages are attributed to. In this case the two passages you cited are both attributed to Jesus. Therefore we have an even stronger case that those alive on the Earth at the time of the 2nd coming will not know the day or hour of His return, whether awake or asleep. To underscore this, Jesus repeated that fact in Matt. 24:42, 24:44, 24:50, and 25:13. Therefore it would not be correct to imply from Rev. 3:3 that those who are awake will know the hour of His return.
The important thing to note from Rev. 3:3 is that Jesus didn’t say, “I will come for you” as in the rapture, but “I will come to you” as in the 2nd Coming. Those who don’t heed His warning to wake up, remember what they’ve been taught, and repent (change their mind about needing to be born again) will miss the rapture.
