tribulation

Definition:

The term "tribulation" refers to a time of hardship, suffering, and distress.

It is explained in the New Testament that Christians will endure times of persecution and other kinds of tribulation because many people in this world are opposed to Jesus' teachings.
“The Great Tribulation" is a term used in the Bible to describe a period of time just before Jesus' second coming when God's wrath will be poured out on the earth for several years.
The term "tribulation" could also be translated as "time of great suffering" or "deep distress" or "severe difficulties."
