Hello yes it is very real and we will be best to simply just wait out the time for its fulfillment.
2 Thessalonians 2:6-12
6 And you know what is keeping him from being here already; for he can come only when his time is ready.
7 As for the work this man of rebellion and hell will do when he comes, it is already going on, but he himself will not come until the one who is holding him back steps out of the way. 8 Then this wicked one will appear, whom the Lord Jesus will burn up with the breath of his mouth and destroy by his presence when he returns. 9 This man of sin will come as Satan’s tool, full of satanic power, and will trick everyone with strange demonstrations, and will do great miracles. 10 He will completely fool those who are on their way to hell because they have said no to the Truth; they have refused to believe it and love it and let it save them, 11 so God will allow them to believe lies with all their hearts, 12 and all of them will be justly judged for believing falsehood, refusing the Truth, and enjoying their sins.
