I have not swamped the OP with a lot of Scripture quotations,
but hopefully you will recall the NT verses which confirm the following …
Man is doubly incapable of believing in Jesus and the Gospel
1 – Because of the disobedience (sin) of Adam and Eve,
all humans are born with an inherited sin nature,
and are bent on sinning instead of following God (Romans 3:9-18).
Having a saving faith is against their very nature!
Without agreeing with the inherited sin part, I do agee this is true in the sense that sinners with lust in the heart, cannot have the faith of our Lord toward God, that is necessary to do His righteousness. Sinners with corrupt hearts of lust must repent of the sinful deeds, to have the heart circumciced from lust and recieve the righteous faith of Jesus Christ toward God, in order to do His will.
Eph{2:8} For by grace are ye saved through faith; and that not of yourselves: [it is] the gift of God:
Scripture reveals that sinful man by his own faith, cannot possibly do His righteousness and please Him. The only faith that pleases God is the faith of Jesus Christ who always pleases Him by the things He does.
Father God elects (chooses) and calls whomever He wishes
Jesus says to the elect, “You did not choose Me, but I chose you ….” (John 16:15).
Surely, here is a strong hint that we should investigate this matter further.
Romans chapter 9 is the most famous proponent of God’s election …
This is again true, in that hearts of sinners corrupted by lust, cannot choose to be servants of the Lord Jesus Christ. Once again, the unrighteous deeds must be repented from, for Jesus to cleanse the heart and life, to become a newly chosen vessel for His rightousness, charity, and godly living in this life, and that to come.
God gives justice to whomever He chooses, and everyone deserves justice!
God judges every man and woman by our works, without exception nor respect of persons.
1 Peter {1:15} But as he which hath called you is holy, so be ye holy in all manner of conversation; {1:16} Because it is written, Be ye holy; for I am holy. {1:17} And if ye call on the Father, who without respect of persons judgeth according to every man’s work, pass the time of your sojourning [here] in fear:
Only the doers of unrighteousness are judged to recieve God's justice of condemnation. His people doing His righteousness are justified with Him by judgment of our works.
God wishes that all could be saved, but it is not possible because He insists on His justice.
It's possible for God to save all men from our sins, but not all men repent of sinning to be saved by Him.
2 Peter 3:9The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
Acts 3:19Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord;
Cor {7:10} For godly sorrow worketh repentance to salvation not to be repented of:
“You love justice and hate evil.” (Hebrews 1”9)
God is not willing that any (of us) should perish, but that all (of us) should repent …
… the “us” referring to His elect, who are promised salvation.
Scripture now calls on all men to repent, the Jew first and also the Gentile, in order to recieve the promise of deliverance from sinning by Jesus Christ,. He is the Advocate for all men, and the propitition for all sins repented of for His sake.
Acts 17:30And the times of this ignorance God winked at; but now commandeth all men every where to repent: Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.
Christians are called to confess and repent of their on-going sins,
and the blood of Jesus will cleanse them of all their unrighteousness (1 John 1:7-9).
If we sin, then we still have the Advocate for the whole world to confess and repent toward Him.
The reason why Father God chooses some, but not others
Father God chooses to elect some people for His great pleasure.
He chooses to elect some to demonstrate to the whole world
His great love, mercy, grace, etc. (Romans 9:23).
He chooses to elect some to be companions for His Son throughout eternity (Scriptural?).
Those not chosen are given justice, which sadly is what they deserve.
God calls upon all men to repent for His Son's sake. He only chooses them that do repent of sins and trespasses.
Mat 22:14For many are called, but few are chosen.
2Ti 2:19Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.
Heb 7:26 For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens;
God is not a hypocrite to justify one transgressor because of their belief alone, while condemning another transgressor doing the same thing.
Rom 2:3And thinkest thou this, O man, that judgest them which do such things, and doest the same, that thou shalt escape the judgment of God?
Gal 6:7Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.
Rom 2:19 For there is no respect of persons with God.
Those whom Father God gives to Jesus are guaranteed salvation
This is all about the unconditional security of the born-again believer.
The only unconditional part of eternal salvation in Jesus Christ, is that we unconditionally surrender to the victorious risen Lord, and unconditional obey Him in all things, even as He does the Father.
Psa 110:1The LORD said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool.
Heb{5:8} Though he were a Son, yet learned he obedience by the things which he suffered; {5:9} And being made perfect, he became the author of eternal salvation unto all them that obey him;
Multitudes of NT verses are God’s promises of salvation given to His elect.
Which are only them obeying Him.
1Pe 1:2Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied.
God has no elect that have not obeyed the call to repent of ongoing sins and trespasses. All disobeying Him are judged children of disobedience by works.
To ensure our calling and election unto the end, we must add to our faith obedience to His virtue, godliness, and charity in all things.
2Pe 1:9But he that lacketh these things is blind, and cannot see afar off, and hath forgotten that he was purged from his old sins.
Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall: For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ.
Surely, those of us who are born again should be continually praising God and
thanking Him for choosing us …
1Sa 15:22 And Samuel said, Hath the LORD as great delight in burnt offerings and sacrifices, as in obeying the voice of the LORD? Behold, to obey is better than sacrifice, and to hearken than the fat of rams.
Mar 12:33 And to love him with all the heart, and with all the understanding, and with all the soul, and with all the strength, and to love his neighbour as himself, is more than all whole burnt offerings and sacrifices.
God inhabits the praises of His saints trusting and thanking Him for obedience from sin.
Hos 14:2Take with you words, and turn to the LORD: say unto him, Take away all iniquity, and receive us graciously: so will we render the calves of our lips.
He does not inhabit the praises of anyone committing ongoing sin in His name.
Isa 29:13 Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me, and their fear toward me is taught by the precept of men:
