Mat 24:5 "For many will come in My name, saying, 'I am the Christ,' and will deceive many."
During the charismatic movement in the 1970s, Christians in all denominations were attracted back to the bible and with truth being revealed to them. Many including professionals and businessmen, gave up their jobs, businesses, comforts, wealths, etc. to serve God. This spiritual revival brought godly Christians closer to the Lord and with better understanding and knowledge of the bible, they found that End time events were still a mystery. So in the1980s and early 90s, many godly Christians were fervently seeking the understanding of end times signs for they wanted to know Him and His words better so that they could do His will. Unfortunately, as usual, revival also draw wolves into the fold. Some went to the bible seminaries for the degree to become professional pastors and teachers. Those so-called famous and anointed teachers (who did not have any revelation of end time mysteries) caused confusions by producing all types of worldly doctrines. The greatest heresy is the Secret Rapture', which completely ignored all Jesus end time teachings. Fear of His imminent Coming was the main factor for the congregation to tithe and give love offerings, making covetous mega-church pastors extremely rich.
Dan 12:4,9 "But you, Daniel, shut up the words, and seal the book until the time of the end; many shall run to and fro, and knowledge shall increase."... And he said, "Go your way, Daniel, for the words are closed up and sealed till the time of the end."
God did not reveal the last days mysteries to His beloved and faithful prophet Daniel for He will only reveal this end time truth in the time of the end or last generation (since 1993AD). So most teachings (before 1993) concerning end time signs and prophecies were based on worldly or even demonic wisdom, where unlearned and proud theologians formulated all types of confusing doctrines; such as Pre-trib (most popular), mid-trib, Pre-Millennium, Post-Millennium Rapture. Brethren, please throw away all those worldly and erroneous (old) End time doctrines and let the Spirit of truth reveals the truth to you.
Many expected Rapture to be way before the year 2000AD
Since all attentions were focused on end times, because godly Christians love to please God, they were all given a great shock when the PLO-Israel Peace Treaty in 1993AD was signed. Covetous pastors and Christian leaders readily accepted and used this PLO-Israel Peace Treaty to further milk their congregations. Churches celebrated this abominable peace treaty, which helped President Clinton to destroy the faith of millions of Christians with a stroke of the pen.
Many shall run to and fro, and knowledge shall increase
If we are living in the end time, then travelling all over the world will be common, cheap and affordable and knowledge will be very, very advanced (esp. in science, medicine, DNA, IT, AI, TV broadcast, engineering, inventions, space, etc. which were unimaginable a century ago).
Brethren, the end is near and have faith in His word (bible) only. Read the Bible, meditate on His word and please fill your mind with His truth. Set your heart to walk out His word without any doubt nor unbelief. Repent of heresies, wickedness, deceptions, lies, worldly wisdom, etc. so that you are right with God. Keep His word and you will know the truth which will help you to do greater exploits esp. the saving of many misled brethren from damnation.
