Mat 24:9 "Then they will deliver you up to tribulation and kill you, and you will be hated by all nations for My name's sake."
The start of the Period of Sorrows is the hatred of all nations for Christians. Why?
2Cor 11:14-15 And no wonder! For Satan himself transforms himself into an angel of light. Therefore [it is] no great thing if his ministers also transform themselves into ministers of righteousness, whose end will be according to their works.
To deceive the world, the Antichrist and his 10 kings will become ministers of righteousness, who will help, serve, comfort and love all mankind. With their demonic powers, they will quickly restore the horrific, disastrous WW3.
So immediately after WW3, the Antichrist will feed and provide jobs in accordance to their skills and abilities for the recoveries and reconstructions of damaged towns, cities, factories, farmlands, schools, etc. Houses or apartments near the places of work will be distributed to each family. All his assistants (government agencies and officials) are so approachable, kind, understanding and efficient that requests or complaints are immediately dealt with. (This was unheard of before WW3 for corruptions abound.)
The whole world will appreciate and love their king (Antichrist) and his righteous ministers and officials, who have given them so much joy, assurance, comfort, care, and security.
One World Religion
Since most wars were religious, the Antichrist will form the 'One World Religion' on the basis that all religious founders are prophets of God. He will rebuild the temple of God for the 'One World Religion' to unite all religions.
Muslims will accept Moses (Judaism) and Jesus (Christianity) as prophets for they are already in the Quran. Having conquered Jerusalem for the Muslims, the Antichrist will be highly respected as a prophet of Allah. His prophecy that Allah wants to dwell amongst them will please the Muslims to immediately pull down 'the Dome' and Al-Aqsa mosque to make way for the temple of God.
To deceive the Jews, he will proclaim that Yahweh only allows the priesthoods to rebuild the temple of God for Him to dwell there. The construction of the temple solely by the Jews will delight the Jews.
What about Christians?
The Muslims and Jews can accept Jesus as a prophet of God, but they will not accept His divinity. For the success of the unity of all religions, Christians must accept that Jesus is divine but only a prophet just like Moses and Mohammed. The denial of the divinity of Jesus will destroy Christianity and our salvation. Fearful, covetous and worldly church leaders will submit and accept this heresy but God fearing and bible believing Christians will reject and rebel against this new heresy of the 'One World Religion' and the Temple of God.
Building of Temple of God
To the world all those who reject this fair, just and peaceful 'One World Religion' are mad, unlearned, stupid and rebellious who are 'war lovers' or 'peace haters'. The whole world having suffered tremendously from the recent WW3 will not tolerate any possibility of future wars, thus they will rise up to persecute and kill all those rebelling against the Antichrist and 'One World Religion'.
When godly Christians try to expose the deceptions of the Antichrist, 'One World Religion', temple of God, etc by teachings, preachings, protests, etc. they will meet the wrath of the people by being persecuted, tortured and martyred for 42 months until Rapture.
