tribulation

Definition:

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

The New Testament says that Christians will endure times of persecution and other kinds of tribulation because many people in this world are opposed to Jesus' teachings.
The Bible uses the term "the Great Tribulation" to describe a period of time 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."
