I think Satan is against anything that is good and powerful from our Lord the almighty. I believe Satan wants to control and reign over all.
It says in the bible. God allows him to go only as far as God wants him to.
Now the time comes and he defeats Satan.
Even satan will tremble says God. God has powers that most of us haven not even touched base with as of yet.
I am not sure if Antichrist and satan are basically the same, not quite understanding that one, however I do know that there are many false prophecies out there. i was just watching one on utube last night and you know the place was like heaven (the grounds the homes) but the guy was obviously a nut case.
He came out dressed as God and stretching out his arms like hello, and they all believed he our God. If God comes the whole world will know. Jesus says, I will come on a cloud and all will have eyes to see me.
Well I consider these false prophecies to be part of satans crowd as well.
