Why can't we know when Christ will return?
Jesus plainly stated that no one can know the day or hour He will return (Matthew 24:36, 44; 25:13; Acts 1:6-7). We may recognize the general period when conditions are right for Him to return (Matthew 24:32-33), but no person will be able to determine the day.
Why won't God let us know the day? Perhaps it is because, if we knew the time, we would lose our focus. The Scriptures teach us that we must be continually centered on this reality. Jesus told us to be alert, spiritually awake, aware and diligent (Matthew 24:42-44; 25:13; Mark 13:33, 35, 37; Luke 21:34-36).
Even though the everyday routines of life will always require our attention, Christ told us to "seek first the kingdom of God" (Matthew 6:33) and pray, "Your kingdom come" (Matthew 6:10). We are not to lose sight of that future reality.
