If the rapture takes place right after the seven years of the Great Tribulation, then we would know the return of Jesus Christ. And we understand that the Scripture says no one can know. Why would a believer stay alert if we knew when He was coming? But, the passages make it clear that since we don’t know, all believers must be in constant readiness for the rapture. That means that Christians have to be busy doing His will and living a life of righteousness and not in sin.
But be alert at all times, praying that you may have strength to escape all these things that are going to take place and to stand before the Son of Man. -Luke 21:36
The word “alert” here suggests that the followers of Jesus Christ must be in a state of holiness, walking in the Holy Spirit—obeying the Word of God in a daily fashion. When Jesus returns, He wants to see us on our knees seeking, His face. And the way we seek the Lord is by putting our faith in action (Luke 18:1-8).
The phrase “praying that you may have strength to escape all these things” means to have the endurance to continue forward—being faithful and not give up on the Lord.
The word “escape” means two things. The first one is to make sure that you have eternal life through faith in Jesus Christ (Hebrews 2:1-3). The second meaning of the word is to be ready for the rapture, as the Greek word for “escape” means “to flee away” so that you would avoid the wrath of God (1 Thessalonians 5:3), which God will pour out in the second half of the Great Tribulation (Revelation 6). And, when you meet the Lord Jesus Christ in the air, you would have accomplished everything that He had assigned for you here on earth
Friend, do you intimately know Jesus? Does Jesus dwell in your heart? If not, don’t wait any longer because He can come at any moment, and you will be left behind.
