Q. Jesus told His disciples on the Mount of Olives that no one could know the day when Christ returns (Mt 24). Paul tells us in Heb. 10:25 that we will know the day Christ returns. Are they contradictory or are they referring to different events?
A. The Bible, being the Word of God, can’t contradict itself, so they must be different. Hebrews 10:25 says,
Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another–and all the more as you see the Day approaching.
The word Day, being capitalized, tells us the writer was referring to the Day of the Lord, which generally refers to the End Times rather than the specific day of the Lord’s return. Notice in Matt. 24:36 that Jesus referred to “that day” meaning the actual day of His return, rather than “the Day” as in Hebr. 10:25.
Since the approaching end times are bringing hardships to many, we’re supposed to help each other avoid becoming discouraged by reminding everyone that for us it means the rapture is even closer.
