Well no matter how you view it, it is conditional. It is conditional on God putting it there. Although there is no eartly condition upon which grace is bestowed, it is still necessary that God grant that grace as a condition to Salvation. I believe the proper term rather than "unconditional" would be "unmerited". God is not arbitrary. He has His reasons. We just don't know what they are.
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.
The Old Covenant was conditional; the New Covenant is not.
