It is interesting that Yeshua was revealed to Israel as being the Lamb of God and the Son of God, when He was baptized by John the Baptizer. (Jn 1:24-34) Yeshua/Jesus did His public ministry for 3 1/2 years. He died at Passover, which means that He would have been baptized around Succot (Feast of Booths/Tabernacles) six months earlier.
The Antichrist, who opposes and seeks to replace the true Christ/Messiah and God, is revealed to be the one when “he sits as God in the temple of God, showing himself to be God”. (2Thes 2:3-4; Mt 24:15; Dan 9:27; 11:36-39) The beast/antichrist is given authority to reign for 42 months, which is 3 1/2 years. (Rev 13:5-8; 12:10-17)
Jesus/Yeshua came bringing salvation for all — Jew and Gentile — who would believe in His name. The Antichrist comes bringing wrath and destruction against those who are called by the name of YHVH God of Israel and of Messiah/Christ.
Jesus rules over all powers, now sitting at the right hand of God in the heavenlies, far above all principality and power and might and dominion, and every name that is named, not only in this age but also in the world to come! (Eph 1:20-21)
Even so, Come, Lord Jesus!
