All change causes stress while the change is occurring; but when the change is completed peace is returned.
In the days when the greatest change of all time shall take place will be the time of the greatest turmoil of all time.
The greatest change the world will ever experience is when Jesus shall set up His Kingdom.
The scriptures teaches us at the time of the return of Christ there shall be a time of great tribulation like the world has never known before.
It uses the simulacrum (something that looks like or represents something else) of a woman traviling with child to describe the world events just before Jesus Christ's return.
Brethren, if you think things are bad now, just wait a little
while.
