Perhaps I am speaking out of turn, but the main thing we must keep in mind of many of these preachers/theologians is this "Eschatology was a lesser focus of their theology!".
I will not say that it was an afterthought in full, but it was, certainly, a lesser concern.
This is NOT to state that their theology was immature or infantile. Not at all! It is simply to state that their larger focus was on other areas of theology, with Eschatology being a secondary or tertiary concern.
