ONE MESSIAH!
The First coming of the messiah was when Christ came to earth to spread the message of salvation and to show the Goodness and Mercy and Grace of GOD.
The Second coming of the messiah{Same Messiah} will come with judgment and with the Sword of His mouth to give{reward}or what is deserving to everyone according to what they have done in the body.
And will destroy the Antichrist and False Prophet with the brightness of His coming and cast them into the lake of fire where they will be tormented day and night forever and ever.
