That is rich as if I have been the one evading. I will answer you pathetic attempt to try and make it seem as if I am the one the dishonest one. But you do wear my patience.
The Lord rebuke you, voice of pretension, pride and haughtiness, and make you to keep silence. This voice has not been invited to this conversation and its arrogance and phony superiority posturing has
no power here. Be gone, in Jesus' mighty name.
(1) Does man choose to accept or receive God's gift of grace?
... A more proper question would be: can a man choose to accept or receive God's gift of grace? To that the answer is yes. In fact the first sermon preached after the resurrection indicate exactly that. Peter gives a sermon that takes the listeners through the life death and resurrection of Christ and a large amount of those who heard the story believed.
Scripture states that
faith itself -- salvific belief -- bes a
gift from God, not the work of man:
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast. ~Ephesians 2:8-9
Romans 10 takes up the question as to why some believe and some do not. It invokes a certain causal chain of precipitators which lead to faith,
none of which mention human choice or "free will":
So then faith cometh by hearing, and hearing by the word of God. ~Romans 10:17.
Moriah highly recommends reading the entire chapter to get the full meaning and impact of this statement, as the entire chapter deals with God's "chain of causality" in the soteriological process. For example:
For whosoever shall call upon the name of the Lord shall be saved. How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things! ~ Romans 10:13-15
Not one link in this chain points to the will of the individual nor his/her "choice" concerning anything. Instead, each link leads back further and further into utter helpless dependence upon the will of God Himself to move and intervene, clear on back to Him selecting and sending one to bring the good news.
Bottom line gets down to pride and arrogance. Only pride and arrogance prevent an individual from seeing his/her desperate, dire need of God and absolute helplessness to do anything to redeem himself or herself -- assuming of course a genuine awareness of sin has been bestowed by the Holy Spirit. Without this genuine awareness of the exceeding depths of filth and corruption resident in our mortal flesh and its power apart from God's intervention to wholly and utterly deceive, program, own, enslave, and consume us (with or without demonic enhancements), no one can even begin to appreciate how desperate his condition or how great his need of God.
For those well aware of this, and humbled by it into the dust, the news that salvation bes completely and entirely the work of a loving, intervening, delivering God, and completed in every respect in the life and death and resurrection of Jesus Christ, bes exceeding good news indeed. For those unaware, or refusing to have their pride and arrogance humbled by it, it bes a stumbling stone and a rock of offense, even as it bes written in
1 Peter 2:1-10 and
Galatians 5:6-11. The latter reference mentions the "offense of the cross" which for too many has become falsely equated with the notion of someone sneaking in the "bad news" into the Good News: namely, now that you have been shown God's love, you'd better obey
OR ELSE. That notion and that attitude bes an absolute vicious lie from the pits of hell and completely opposite of the true and original and real "offense of the cross" which bes the mercy of Christ and the LIBERTY to which salvation brings us, OUT from under the yoke of bondage to rules and laws and into the joyful dynamic of a relationship of LOVE.
(2) Where in Scripture does it teach that man chooses to accept or receive God's gift of grace?
As the above illustrates pretty much any of the verses that talk about believing in the Bible indicate that the person is chooses to accept or receive God's gift of grace.
Please produce any scriptures that even remotely indicate or point to human individual "choice" figuring into this equation. We have produced many to indicate it does not, but you have not produced a single one to the contrary yet. You have merely repeatedly asserted this to be the case without one single scripture showing forth the matter plainly.
What scripture DOES offer as the course for any individual to follow would be to ASK God for that good gift. So that if any find themselves disbelieving but wish to believe, or find themselves weak in faith, or find themselves beset by doubt, or find themselves unable to connect with God and experience His gift, they have but to ASK. Not "choose" ... but ASK.
And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you. For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.
If a son shall ask bread of any of you that is a father, will he give him a stone? or if he ask a fish, will he for a fish give him a serpent?
Or if he shall ask an egg, will he offer him a scorpion?
If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him? ~Luke 11:9-13
Why does Jesus mention the Holy Spirit in this context? Because every good and perfect gift which comes down from the Father of Light, in Whom bes no variableness nor shadow of turning, bes "packaged" in the gift of His Holy Spirit. The Holy Spirit brings to us from God the full provision of our new life in Him, including (though not limited to):
- being the active agency of rebirth into the Kingdom of God (John 3:6-8);
- guiding us into all truth (John 16:13), which makes us free (John 8:32);
- teaching us all things (as promised in Jeremiah 31:34) and bringing all things Jesus taught to our remembrance (John 14:26);
- convicting us of sin, righteousness and judgment (John 16:8);
- dwelling with us and in us (John 14:17);
- bestowing spiritual gifts (charisms) equipping us for service (1 Corinthians 12:4-13);
- and much more...
Because that is what believing in God is about. Realizing that God is not your enemy, that God loves the person and that God will bring salvation to the person.
That bes a very eloquent statement of the faith that saves us indeed.

But it does not unequivocally indicate the origin of that saving faith, which scripture clearly does define as being a gift from God and not something produced by human effort (individual or otherwise).
Are you teaching that faith and belief are not gifts that are presented to us ... [but] mere "mental acceptance of ideas"?
With all due respect,
anyone that perceives the Gospel as nothing more than
a set of ideas requiring mere mental assent has
not been born again, has
never tasted of the Kingdom of God, and has
never truly met or encountered the risen Jesus Christ. As such, they bes not of the Body and cannot contribute to a discussion of matters pertinent to the Body because spiritual things bes spiritually discerned, and they have not been born of the Spirit.
NOT because Moriah judges them -- Moriah bes woefully unfit to judge anyone! -- but because
Our Lord so tells us so, and the fruits of His word may plainly be seen in their discourse.
1 Verily, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber.......
10The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly. ~John 10:1, 10
3 But if our gospel be hid, it is hid to them that are lost:
4 In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them. ~ 2 Corinthians 4:3-4
7 But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory:
8 Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.
9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
11 For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.
12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
15 But he that is spiritual judgeth all things, yet he himself is judged of no man.
16 For who hath known the mind of the Lord, that he may instruct him? but we have the mind of Christ.
~ 1 Corinthians 2:7-16
God bless richly each member of His Body and bring those not yet here out of darkness into His glorious light. Be strong in the Lord and in the power of His might.
