As Christians, we must ensure that we are caught up at Rapture (1st resurrection). To be able to be part of Rapture, we must keep His words, believe and obey His warnings concerning the last days, and also understand the Endtime Signs of Jesus, so that we can overcome the final persecutions, temptations and deceptions of Satan.
Without the understanding of Endtime truth, we will likely be deceived and loose our salvation for :-
1. bowing down and worship the Antichrist as god, when he is seated in the new temple of God build by the blind and misled Jewish Priesthood,
2. the desire to be implanted with the Micro Biochip (mark of the beast '666'), which can monitor our blood system and detect and destroy harmful viruses and cancer cell, thereby giving very long lifespan with healthy bodies.
Rev 14:9-11 Then a third angel followed them, saying with a loud voice, "If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation. He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name."
Beware Brethren - All those who have worshipped the Antichrist as God and have been implanted with the biochip (666) will be left behind and then condemn to the Lake of fire.
To us, anything after Rapture is for educational purpose and also for the complete understanding of endtime signs and prophecies.
