I agree, but only because saving faith is only given by God. From your perspective God opens the door, but it is up to man to walk through it.
Saving faith is not given by God. Faith is being persuaded of the truth that Jesus is who He claims and the only name by which to be saved. God certainly provides the persuasive evidence (Christ's death & Ressurection, conviction of the Spirit, Scripture, the preaching of the gospel, etc.) but He doesn't make anyone believe it is true.
Scripture, over and over, places the command to believe upon man. (Acts 20:21, Rom 10:16-17, I Thess 2:13, Gal 3:2, etc.) To perform the work of God (vs. dead works of righteousness) we must believe in the one He sent (Jn 6:28-29.)
Indeed, the gospel is, 'believe for the forgiveness of sins,' (Acts 10:43) not, 'well, some of you listening are among the chosen few that God makes believe and not among the many that just can't believe. If you get that belief, then, congrats! If you can't believe, well, nothing you can do about it.'
What does it mean that it is by grace we have been saved, through faith, and that this is not of ourselves but is the gift of God?
How are we to understand the sequence and part that man plays in his salvation?
What does it mean that Jesus is the author and perfecter of our faith?
Also, how can you say you're not 'better' than the non-believer down the road, then turn around and say you're more receptive to the Holy Spirit than others? Isn't having a heart more receptive to God a better trait than having a hardened heart which rejects Him?
It is not pride, since faith is in every way contrasted with boasting. Is it better in the eyes of God to have humility and admit one's own sin? Certainly - but humility is the opposite of pride, not a mark of pride. One isn't 'better' than another fallen human for being willing to admit the depths of your sin while the other is not.
Faith is in every way contrasted with boasting, for it is based in humility, in a proper regard for one's position in regard to Christ. If a man proclaims, "I have placed my faith in Christ!" this is not a boast, but humility, for he is testifying that, "I was a sinner under condemnation for my wicked deeds, one in need of salvation, a salvation that only Jesus the Messiah could provide. I believe the Messiah is who He claims, with all authority given to Him. I have repented and given my life to Him, have died to myself and risen with him, and God for the sake of Christ's righteousness and His glory shall grant me eternal life."
What does it mean in Rom 3:27 that boasting is excluded because of the law that requires faith?
The idea that a person acknowledging his sin and turning to the only one who can save him in faith is
'boasting' is nowhere taught, nor implied, in scripture.
I agree that it is humbling to be a recipient of true faith. I don't agree that you, or he, or I, had any part in it. That is why no man can boast.
We are recipients of salvation through faith, not recipients of faith. It is humbling because faith in the work and person of Christ is the required method - not any dead works of the law we could do on our own.
"Therefore no one will be declared righteous in God’s sight by the works of the law; rather, through the law we become conscious of our sin. But now apart from the law the righteousness of God has been made known, to which the Law and the Prophets testify.
This righteousness is given through faith in Jesus Christ to all who believe. (Not, 'this faith is given so that some may believe and be righteous') There is no difference between Jew and Gentile,
for all have sinned and fall short of the glory of God, and all are justified freely by his grace through the redemption that came by Christ Jesus. God presented Christ as a sacrifice of atonement, through the shedding of his blood—to be received by faith. (Not, 'God gave some faith in Christ so that those few would be atoned for.') He did this to demonstrate his righteousness, because in his forbearance he had left the sins committed beforehand unpunished— he did it to demonstrate his righteousness at the present time, so as to be just and the one who justifies those who have faith in Jesus.
Where, then, is boasting? It is excluded. Because of what law? The law that requires works? No, because of the law that requires faith. For we maintain that a person is justified by faith apart from the works of the law. - Rom 3:20-28
Also, let's not forget the countless scriptures telling us to 'hold firm our confidence, (Heb 3:6)' 'hold fast' to faith (I tim 1:19) lest we suffer shipwreck, see that what we heard from the beginning remains in us' (I Jn 2:24) so that we may remain with the Father, hold our conviction firm to the very end (Heb 3:14, etc.) and other exhortations to continue to remain in Christ through faith and to hold fast to our faith.
