Thankfully, the days are long gone when we think that an aorist verb automatically describes a punctiliar action. No more describing the aorist as the bat hitting the ball (although the error is still present in some older commentaries).
I was reading Miller’s latest book, Scary Close, and it reminded me of a verse that illustrates the aorist.
What is discipleship? What is it to be a Christian (since all Christians must be disciples)? Jesus tells us in Mark 8:34. “If anyone would come after me, he must deny himself (ἀπαρνησάσθω), take up (ἀράτω) his cross and follow (ἀκολουθείτω) me.”
The aorist ἀπαρνησάσθω may suggest that the denial is a once-off event, as might the aorist ἀράτω. In this case, both words would be referring to conversion.
