The end time (also called end times, end of time, end of days, last days, final days, or eschaton) is a future time-period described variously in the eschatologies of several world religions (both Abrahamic and non-Abrahamic), which believe that world events will reach a final climax.

The Abrahamic faiths maintain a linear cosmology, with end-time scenarios containing themes of transformation and redemption. In Judaism, the term “end of days” makes reference to the Messianic Age and includes an in-gathering of the exiled Jewish diaspora, the coming of the Messiah, the resurrection of the righteous, and the world to come. Some sects of Christianity depict the end time as a period of tribulation that precedes the second coming of Christ, who will face the Antichrist along with his power structure and usher in the Kingdom of God.

Christian eschatology is a major branch of study within Christian theology dealing with the “last things.” Eschatology, from two Greek words meaning “last” (ἔσχατος) and “study” (-λογία), is the study of ‘end things’, whether the end of an individual life, the end of the age, the end of the world and the nature of the Kingdom of God. Broadly speaking, Christian eschatology is the study concerned with the ultimate destiny of the individual soul and the entire created order, based primarily upon biblical texts within the Old and New Testament.

Christian eschatology looks to study and discuss matters such as death and the afterlife, Heaven and Hell, the second coming Jesus, the resurrection of the dead, the rapture, the tribulation, millennialism, the end of the world, the Last Judgment, and the New Heaven and New Earth in the world to come.

Eschatological passages are found in many places in the Bible, both in the Old and the New Testaments. There are also many extrabiblical examples of eschatological prophecies, as well as church traditions.

Matthew 3:2 English Standard Version (ESV)
2 “Repent, for the kingdom of heaven is at hand.”[a]

Yes, church should preach the message about the Kingdom of God rightly; just like Apostle Paul, "
boldly and without hindrance he preached the kingdom of God and taught about the Lord Jesus Christ.
(Acts 28:31)"
