By "in" here, I mean "in the faith", "in Christ" and so forth.
When I was in Charismania,
my Arminian teachers warned:
- faith got you in, faith will keep you in.
then I swang to Calvinism and this got transformed to
- grace got you in, grace will keep you in.
None of these gave assurance. I did not find all the above adequate as the first points to me or my faith, while the second points to me again, I am sure that comes as a surprise, correct? The second also points to me because here is the question: did this grace "happen" to me? In effect, did this faith which is a gift of God happen to me? Both point to something in me. Both get me edgy.
My assesment, and I believe is consistent with the Scripture's teaching on the means of grace:
- The Gospel that got you in, is the same Gospel that keeps you in.
The Lutherans Confessions taught me the last one and it points me to the Promise, outside me.
Now, if I could get these Lutherans excited and believe their own doctrine and trust the means of grace...
