That’s what seems to be the case here.
I’m sure you can see my concern.
If you are saved, then how can your sins ever make you unsaved again?
The atonement for sins is/was Christ's one-time sacrifice, the perfect once-and-for-all sacrifice that we participate in, in each Eucharistic celebration (as the Prophet Micah spoke about the prayers being all the time, across the world)
His Salvation saves us in the continuous sanctification.
it's like (a bad analogy) we get on a bus and someone before us has paid for us already. We just have to accept this payment. Of course it's a bad analogy as we ourselves can't pay for the ticket no matter what we do. AND, it's not just "oh, he paid, now let me do what I like" but as Jesus said Repent, believe, be baptised, eat of My body and blood and endure to the end"/
