Jesus tells about remaining Watchful - Matthew 24:36-51 ... Excerpt from the Bible

It is good we don't know exactly when Christ will return. If we knew the precise dates, we might plan to keep sinning and then turn back to God right at the end. Heaven is our only goal; we have work to do here. We must keep on doing it until death or until we see the unmistakable return of our Savior.

Christ's Second Coming will be swift and sudden. There will be no opportunity for after thought., last-minute repentance, or bargaining. The choice we have already made will determine our eternal destiny.

Jesus purpose in telling about his return is not to stimulate predictions and calculations about the date, but to warn us to be prepared. Will you be ready? The only safety is to obey him today.

Jesus asks us to spend the waiting time taking care of his people and doing his work on earth, both within the Church and outside of it. This is the best way to prepare for Christ's return.

Knowing that Christ's return will be sudden should motivate us always to be prepared. We are not to live irresponsibly - sitting and waiting, doing nothing; seeking self-serving pleasure, using his tarrying as an excuse not to do God's work of building his kingdom; developing a false security based on precise calculations of events; or letting our curiosity about the end times divert us from doing God's work.

"Weeping and gnashing of teeth" is a Phrase used to describe despair. God's coming judgment is as certain as Jesus' return to earth.
