Is it possible that both Christ and the Antichrist could rise at any moment ?
God knew that the Antichrist comes first because there are no worthy Christians out there that are willing to fight alongside Him and transform this world now.
The Christians of today believe that there will be this Rapture hence they are unwilling to take up the reigns thus bypassing the 7 Year Tribulation.
God knew this, hence Scripture tells of the Antichrist and the Third Temple along with the Mark, coming first.
Then after 7 Years of Tribulation, people get fed up and revolt. Thats when the real Christ enters this world arena.
