Dispensationalists believe in God and Jesus. Using your logic, that makes you a dispensationalist. If someone says that they are not a dispensationalist - don't argue otherwise. I am not a dispensationalist.You pretty much are. You can't convince me otherwise.
Because you are a dispensationalist. That is what dispensationalists believe. The idea of a singular future Antichrist comes from dispensationalism as does the idea of the rapture occurring separately some time before the return of Christ in vengeance against His enemies.
The core basis of dsipensationalism is that man's history can be categorized as 7 blocks of time, called 7 dispensations, such as, law, grace. etc. I copied and pasted this chart from an online source.
