I followed you and agree with you right up to the point where you started talking about what the primary cause of a bad relationship with God is. “Bad doctrine”??? Really? I’d think sin is the primary cause of a bad relationship with God. At times, I’ve even thought about stopping by my local RCC church and doing a little confessing there myself.
I’m including in my agreement the part that I've never seen you discount Grace and/or its power too. I thought that was a bit unfair toward your position as well. But then again, I kind of see his point as well (kind-of).
But anyway, (and it's a big but) my OSAS doctrine places the primacy of relationship squarely between a Christian and
the Holy Spirit indwelling within them. Not on any external doctrine (including mine) or with other people (including my wife).
I’ve never actually seen a cogent/evidential response from the anti-OSAS side as to why Paul (who got the idea from God of course, Luke 11:13, 12:12) would say what he did here:
For all the promises of God find their Yes in him. That is why it is through him that we utter our Amen to God for his glory. And it is God who establishes us with you in Christ, and has anointed us, and who has also put his seal on us and given us his Spirit in our hearts as a guarantee.
(2 Corinthians 1:20-22 ESV)
Something about Tupperware and an earthly king’s seal being breakable, as I recall. Which misses Paul’s point entirely in my opinion. Or else, the balancing act thing that must be applied to Scripture, as if one Scripture pulls down and one pulls up and it’s our job to balance them out in the middle.
