SOOOOO many people overlook the verb tenses of the Greek N.T.......man.....it settles a bunch of questions and puts to bed a bunch of false theology....
I agree...I love the perfect tense and the ramifications of what that means when we read that in a verse. The Greek listener would know exactly what that meant when he heard the perfect tense being used especially when used in the passive voice.
For example Eph. 2:8
By grace You have been saved through faith. Have been saved = perfect passive.
