Exactly. Well put.
God's grace is available to all. Christ died for the world.
Grace -- at some point determined only by God Himself -- has its limits...and cannot ALWAYS 100% FOREVER to be assumed...and those limits occur at some point where Jesus Christ is being PUBLICLY disgraced:
Here's "Scripture" on that:
4 It is impossible for those who have once been enlightened, who have tasted the heavenly gift, who have shared in the Holy Spirit, 5 who have tasted the goodness of the word of God and the powers of the coming age 6 and who have fallen away, to be brought back to repentance. To their loss they are crucifying the Son of God all over again and subjecting him to public disgrace. (Hebrews 6:4-6)
We know God -- on His side -- won't let loose any believer...for God is faithful...but at some point people "who have shared in the Holy Spirit" CAN commit spiritual suicide. Grace cannot forever be presumed. And, as we know, grace IS a "condition" for salvation.
My post #188. The Old Covenant was conditional (agreement between parties). The New Covenant is not.
