10 Questions about OSAS

More likely a Memist.

Or Molinist .

Umm, it's a beauty mark.

It depends on whether you had your money on the bird or the target.

I looked at an overview of Molinism did construct a ROSES without realizing that Molinism already has its own ROSES so there may be something to your evaluation, although there is something I read in the overview that seemed quite objectionable attached to the movement though I forget what since I've never readily attached myself to any particular sect.

Psalm 119: 108 mentions freewill so, although many may without qualm, I cannot reject its existence, and it is what I suspect as the cause as much as it is God's grace that provides for it.

Accept the freewill offerings of my mouth, O LORD,
and teach me Your judgments. -Psalm 119: 108 contained with the "Nun" section which begins "Your word is a lamp to my feet
and a light to my path (v.105)." noting that "Nun" denotes a son (or daughter by implication) as illustrated in v. 111 "Your testimonies are my heritage forever, for they are the joy of my heart." This is followed by the "Samech" verses 113-120, which denote a shield as illustrated by v. 114, "You are my hiding place and my shield; I put my hope in Your word." and reflects my adoption in eternal security in v. 116, "Sustain me as You promised, that I may live; let me not be ashamed of my hope."

I don't know if that's Molinism, but it definitely is Meminist.

the last "it" was meant to, more specifically, refer to sin, as the first "it" refers to freewill.

Oh, and I probably should've inserted "atonement" in between 'provides' and 'for.'

I want to understand your position more clearly.
Do you mind if I investigate your position with some questions?

Of course it is Calvinism. How come you are so confused? Calvinism and Reformed Theology are identical.

Because someone has a reformed understanding of scripture doesn't make one a Calvinist. Calvin was hardly the only reformer. And, believe it or not, it is possible to hold reformed beliefs simply through scripture alone.
Calvinism has become an umbrella under which those who are not reformed place all who are reformed. But there is much disparity amongst those who hold to a reformed biblical understanding. Because this is ill-understood, any word using some derivation of the word Calvin has become tantamount to a slur.
Christians are smart enough to be able to work through individual doctrines without labels.

Spoken like a true Calvinist.

That's what you get when you back a Calvinist into a corner...he is predestined to fight.

Then why were you not smart enough to recognize that both Calvin and Reformed Theology hold to the eternal security of the believer? You denied this and had to be corrected.

"The Reformed view, which was championed by the influential French theologian, John Calvin, states that salvation can only come to those who are truly called. Because the Bible explains that God’s calling is irrevocable, this view teaches that the true “regenerate” believer can never lose his salvation."

If you read the post more carefully, you will see that I didn't say both don't adhere to this doctrine. I merely said that one doesn't have to come to this realization.

Bible Exposition Commentary – Be Right (Romans)

To say that the olive tree, with its natural and grafted branches, is a picture of the church would be a great mistake. In the church, "there is no difference"; believers are "all one in Christ Jesus" (Gal. 3:28). God does not look on the members of Christ's body and see them as Jews or Gentiles. The olive tree illustrates the relationship between Jew and Gentile in the program of God. The "breaking off of the branches" is the equivalent of "the fall" (Rom. 11:11), "the diminishing" (Rom. 11:12), and "the casting away" (Rom. 11:15). To read into this illustration the matter of the eternal destiny of the individual believer is to abuse the truth Paul was seeking to communicate.

Teacher's Outline and Study Bible – Romans, Volume 2:

. The goodness of God is seen in the grafting in and acceptance of the Gentiles by God. But note the stress of this point: the goodness of God is given only to those who continue in God's goodness. A person who knows about the love of God must walk and live in God's goodness. The word "continue" means to remain, be steadfast, abide, persevere, endure. The idea is both position and relationship.

It is the picture of a person who is remaining and abiding in the house of God's goodness. A Gentile believer must continue and abide, endure and persevere in the goodness of God, or else he too will be cut off just as the Jews were cut off (Romans 11:17).

He that endures to the end shall be saved

Vincent's Word Studies in the New Testament.

Romans 11:22
Goodness and severity (χρηστότητα καὶ ἀποτομίαν)

For goodness, see on 3:12. Ἁποτομία severity, only here in the New Testament. The kindred adverb, ἀποτόμως sharply, occurs 2 Corinthians 13:10; Titus 1:13. From ἀποτέμνω to cut off. Hence that which is abrupt, sharp.

Thou shalt be cut off (ἐκκοπήσῃ)
Lit., cut out. See on Luke 13:7.

Word Pictures in the New Testament.

The goodness and the severity of God (chrēstotēta kai apotomian theou). See on Romans 2:2 for chrēstotēs, kindness of God. Apotomia (here alone in the N.T.) is from apotomos, cut off, abrupt, and this adjective from apotemnō, to cut off. This late word occurs several times in the papyri.
If thou continue (ean epimenēis). Third class condition, ean and present active subjunctive.
Otherwise (epei). Ellipse after epei, "since if thou dost not continue."
Thou also (kai su). Precisely as the Jewish branches of Romans 11:17 were.
Shalt be cut off (ekkopēsēi). Second future passive of ekkoptō, to cut out.
