It matters deeply if you believe the Antichrist is the Messiah because you haven't studied your Bible. Knowing how things happen in what order prevents one from being deceived.

Luke 21:8-19

8 And he said, Take heed that ye be not deceived: for many shall come in my name, saying, I am Christ; and the time draweth near: go ye not therefore after them.

9 But when ye shall hear of wars and commotions, be not terrified: for these things must first come to pass; but the end is not by and by.

10 Then said he unto them, Nation shall rise against nation, and kingdom against kingdom:

11 And great earthquakes shall be in divers places, and famines, and pestilences; and fearful sights and great signs shall there be from heaven.

12 But before all these, they shall lay their hands on you, and persecute you, delivering you up to the synagogues, and into prisons, being brought before kings and rulers for my name's sake.

13 And it shall turn to you for a testimony.

14 Settle it therefore in your hearts, not to meditate before what ye shall answer:

15 For I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist.

16 And ye shall be betrayed both by parents, and brethren, and kinsfolks, and friends; and some of you shall they cause to be put to death.

17 And ye shall be hated of all men for my name's sake.

18 But there shall not an hair of your head perish.

19 In your patience possess ye your souls.
