One may ask, why must the Lord take the Church back to Heaven before the Tribulation Years start? In the Old Testament, God had given many examples of His ‘plucking’ His chosen ones out before He sent judgement upon the land.
Because of Adam’s sin, this planet was handed over to the Devil for him to rule over. When God created the Heavens and the Earth and everything in it, the Lord gave the keys to Adam to have dominion over everything. But Adam sinned and disobeyed God in not keeping the Lord’s command not to eat of the Tree of Knowledge of Good and Evil. Man was meant to eat from the Tree of Life so that he can live forever but he chose to eat of the Tree of Knowledge of Good and Evil and so God had to drive him and his wife Eve out of the Garden of Eden so that he cannot subsequently eat of the fruit of the Tree of Life and thereafter live in perpetual condemnation without hope of redemption. Because Adam and Eve listened to the Devil and disobeyed God, he forfeited his rightful position of glory and blessedness and thereafter the authority was transferred to the Devil.
Now God foreknew this would happen and He had already hatched a plan of salvation to redeem the spirits of mankind through the shedding of the Blood of His Son. Because God had already given mankind the gift of choice, He had to honour that covenant and hence He chose His own timing to execute His Redemption Plan.
After Adam and Eve sinned and ate of the fruit of the Tree of Knowledge of Good and Bad, the Lord prophesied of the serpent (Devil was in the serpent).
Genesis 3: 14-15 -
v14 “Because you have done this, you are cursed more than all cattle, and more than every beast of the field; On your belly you shall go, and you shall eat dust all the days of your life.
v15 And I will put enmity between you and the woman, and between your seed and her Seed; He shall bruise your head, and you shall bruise His heel.”
So the Devil had been looking out for the Seed of the woman to ensure that the prophecy would not come to past. The Devil caused Cain to murder Abel (Genesis 4) thinking that that would end the human race but God gave Adam and Evil another son (Seth) to carry on the bloodline. And the Devil thought he could frustrate God’s plan of salvation by corrupting the human race - he instigated some of the fallen angels to cohabitate with the human women and cause their children to be born as giants (rephaim).
This was not part of God’s original plan for mankind and so He decided to wipe out these giants. However, because God is a just and righteous God, He restrained Himself and did not send judgement immediately. Instead, He gave them a warning - He caused Enoch to have a son and asked him to name the boy Methuselah. This boy was to be a living wake-up call to repentance because his name meant “his death shall bring” - and the people knew that judgement will come as soon as Methuselah dies. Imagine every day, the first thing the people would do is to check whether Methuselah was still alive.
Because God is patient, Methuselah became the oldest living person in all creation - he lived to the age of 969 years and history had it that shortly after Methuselah died, God sent the Flood to destroy every living thing on Earth - every animal and bird in the air - except those that God saved in the ark that Noah (Methuselah’s grandson) built.
Enoch, Methuselah’s father, was taken out of this Earth when he was 365 years old and he did not die because the Lord took him home bypassing the physical death stage. Now, one may ask why did the Lord not let Enoch die a physical death but took him back to Heaven? I submit to you that the Lord wants to use Enoch’s life to be a witness for all Christians alive today that He will do the same for us at the Rapture - the snatching up of the Saints (in Greek, it is ‘harpadzo’).
