Thanks for sharing what you believe provides the biblical support for the "gift of faith."
My version of Hebrews 12:2 does not read, "...author and finisher (perfecter) of our faith." It reads, "...author and perfecter of faith." God created us with the capacity to trust in what we believe is the truth, and God provided through Christ, the message of the truth, the gospel of Christ. That makes God the author and perfecter of faith. So based on my understanding of this verse, it provides no support whatsoever for the "gift of faith."
The ESV, the HCSB, the NET and the NKJV adds "our" to the text, but it is not found in the Greek. The NASB, the NIV, YLT, Darby, and Wycliffe do not add "our."
My version of Philippians 1:29 does not read, "...The only ones who believe are those whom God grants the gift of faith." It reads, "For to you [Philippian believers] it has been granted for Christ's sake, not only to believe in Him, but also to suffer for His sake." What this says is God did not preclude the Philippians from believing, He did not harden their hearts, and it also says He did not intervene and protect them from suffering for Christ's sake, He allowed it. So based on my understanding of the verse, it provides no support whatsoever for the gift of faith.
My version of 2 Thessalonians 2:13 does not read, "who God chooses to believe truth." It reads, ...,"because God has chosen you from the beginning [or as firstfruit] for salvation through sanctification by the Spirit and faith in the truth." Thus it says God chose you based on faith in the truth, rather than to give you faith in the truth. So based on my understanding of the verse, it provides no support whatsoever for the gift of faith.
1 Corinthians 1:26-30 says God chooses ...things of this world, which puts the order, as being called, then being chosen. So God chooses those who respond to the call by trusting in Christ as determined by God who credits or not, our faith in Christ as righteousness, Romans 4:4-5.
Acts 13:48 does not say God appoints people so they believe. The word translated appointed mean an agreement by mutual consent, thus God, through Paul, laid out the requirement, and the Gentiles agreed, and therefore as many as had been appointed to eternal life believed. They took Paul's direction to eternal life which required them to trust in Christ.
So no support for the gift of faith yet again.
And finally, God does not necessarily give to Christ everyone He draws with lovingkindness. Only those who have both understood and learned from the Father are given, and so the second and third soils of Matthew 13 understood but did not learn as required by God, and so were not given.
At the end of the day, there is no support in scripture for the so called "gift of pre-salvation faith."
In the Greek, I believe yet I know no Greek, it reads author and finisher of the faith.
I also do not know much more English, schooling wasn't my high point, so what happens when the definite article in front of a word.
Here is what I think it says and brings out truth from the word.
Looking unto Jesus the author and finisher of the faith; That is the faith that comes by obedience. Or as Paul would say obedience of faith. Oddly enough where this phrase is used Rom. 1:5 and 16:26 (the) precedes it and it is not in the Greek.
Following in V-2 speaks of this obedience: endured the cross, despising the shame. See also Heb. 5:8 Though he were a Son, yet learned he obedience by the things which he suffered; Also Phil. 2:8 and became obedient unto death, even the death of the cross.
I know he was God he didn't need faith. Maybe so, maybe not.
Heb. 5:7 Who in the days of his flesh, when he had offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and was heard in that he feared; Luke 22:42 Saying, Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done. Luke 22:44 And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground. Hebrews 12:4 Ye have not yet resisted unto blood, striving against sin.
Am I the only one who sees the fear of death here? Was this easy for the Word made flesh? Did it require any obedience? Faith? Luke 23:46 and having cried with a loud voice, Jesus said, `Father, to Thy hands I commit my spirit;' and these things having said, he breathed forth the spirit. He, Jesus the person died and his body (That which would perish in time) still hung on the cross. Acts 13:30 But God raised him Jesus) from the dead: Gal. 1:1 Paul, an apostle, (not of men, neither by man, but by Jesus Christ, and God the Father, who raised him (Jesus) from the dead;)
For by grace are ye saved through faith; KJV for by grace ye are having been saved, through faith, YNG
I notice (the) is not before faith in either translation yet I believe it to be there but as I said I know no Greek.
Need some scholar help.
