where does the story of the Good Shepherd suggest no choice? It's a parable about the Shepherds care not the sheep's defiance
Believe me when I say that we are in agreement. However, it is the scripture most often used to support the OSAS
When he has brought out all his own, he goes on ahead of them,
and his sheep follow him because they know his voice. But they will never follow a stranger; in fact, they will run away from him because they do not recognize a stranger’s voice.”
John 10:4-5 NIV
Now this is just one example of many. When all the examples regarding this topic are collected and reviewed. IMO the argument could reasonably go both ways depending on context. I personally have found free will to be more convincing.
Here is the evidence in support of OSAS:
(a) Romans 8:30 declares, "And those He predestined, He also called; those He called, He also justified; those He justified, He also glorified." This verse tells us that from the moment God chooses us, it is as if we are glorified in His presence in heaven. There is nothing that can prevent a believer from one day being glorified because God has already purposed it in heaven. Once a person is justified, his salvation is guaranteed - he is as secure as if he is already glorified in heaven.
(b) Paul asks two crucial questions in Romans 8:33-34 "Who will bring any charge against those whom God has chosen? It is God who justifies. Who is he that condemns? Christ Jesus, who died more than that, who was raised to life - is at the right hand of God and is also interceding for us." Who will bring a charge against God's elect? No one will, because Christ is our advocate. Who will condemn us? No one will, because Christ, the One who died for us, is the one who condemns. We have both the advocate and judge as our Savior.
(c) Believers are born again (regenerated) when they believe (John 3:3; Titus 3:5). For a Christian to lose his salvation, he would have to be un-regenerated. The Bible gives no evidence that the new birth can be taken away.
(d) The Holy Spirit indwells all believers (John 14:17; Romans 8:9) and baptizes all believers into the Body of Christ (1 Corinthians 12:13). For a believer to become unsaved, he would have to be "un-indwelt" and detached from the Body of Christ.
(e) John 3:15 states that whoever believes in Jesus Christ will "have eternal life." If you believe in Christ today and have eternal life, but lose it tomorrow, then it was never "eternal" at all. Hence if you lose your salvation, the promises of eternal life in the Bible would be in error.
Here is the evidence against OSAS:
Mark 4:16 (Luke 8:13) "And in a similar way these are the ones on whom seed was sown on the rocky places, who, when they hear the word, immediately receive it with joy; (they believe for a while) and they have no firm root in themselves, but are only temporary; then, when affliction or persecution arises because of the word, immediately they fall away.
Galatians 5:4 "You have been severed from Christ, you who are seeking to be justified by law; you have fallen from grace."
John 15:5-6 "I am the vine, you are the branches; he who abides in Me, and I in him, he bears much fruit; for apart from Me you can do nothing. If anyone does not abide in Me, he is thrown away as a branch, and dries up; and they gather them, and cast them into the fire, and they are burned."
Romans 11:19-23 "You will say then, "Branches were broken off so that I might be grafted in." Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear; for if God did not spare the natural branches, neither will He spare you. Behold then the kindness and severity of God; to those who fell, severity, but to you, God's kindness, if you continue in His kindness; otherwise you also will be cut off. And they also, if they do not continue in their unbelief, will be grafted in; for God is able to graft them in again."
Hebrews 6:4-6 For in the case of those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit, and have tasted the good word of God and the powers of the age to come, and then have fallen away, it is impossible to renew them again to repentance, since they again crucify to themselves the Son of God, and put Him to open shame.
Hebrews 10:26-27 For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but a certain terrifying expectation of judgment, and the fury of a fire which will consume the adversaries."
Hebrews 10:38-39 "But My righteous one shall live by faith; And if he shrinks back, My soul has no pleasure in him. But we are not of those who shrink back to destruction, but of those who have faith to the preserving of the soul."
Acts 20:17,28-30 "And from Miletus he sent to Ephesus and called to him the elders of the church." ... "I know that after my departure savage wolves will come in among you, not sparing the flock; and from among your own selves men will arise, speaking perverse things, to draw away the disciples after them."
1 Timothy 1:18-21 "fight the good fight, keeping faith and a good conscience, which some have rejected and suffered shipwreck in regard to their faith. Among these are HYMENAEUS and Alexander"
2 Timothy 2:16-18 But avoid worldly and empty chatter, for it will lead to further ungodliness, and their talk will spread like gangrene. Among them are HYMENAEUS and Philetus, men who have gone astray from the truth saying that the resurrection has already taken place, and thus they upset the faith of some.
1 Timothy 4:1 "But the Spirit explicitly says that in later times some will fall away from the faith, paying attention to deceitful spirits and doctrines of demons"
1 Timothy 6:20-21 "O Timothy, guard what has been entrusted to you, avoiding worldly and empty chatter and the opposing arguments of what is falsely called "knowledge"-which some have professed and thus gone astray from the faith."
2 Peter 2:1 "But false prophets also arose among the people, just as there will also be false teachers among you, who will secretly introduce destructive heresies, even denying the Master who bought them, bringing swift destruction upon themselves."
2 Peter 3:17 "You therefore, beloved, knowing this beforehand, be on your guard lest, being carried away by the error of unprincipled men, you fall from your own steadfastness"
2 John 8-9 "Watch yourselves, that you might not lose what we have accomplished, but that you may receive a full reward. Anyone who goes too far and does not abide in the teaching of Christ, does not have God; the one who abides in the teaching, he has both the Father and the Son."
1 Timothy 6:9-10 "But those who want to get rich fall into temptation and a snare and many foolish and harmful desires which plunge men into ruin and destruction. For the love of money is a root of all sorts of evil, and some by longing for it have wandered away from the faith, and pierced themselves with many a pang."
2 Peter 2:20-22 "For if after they have escaped the defilements of the world by the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and are overcome, the last state has become worse for them than the first. For it would be better for them not to have known the way of righteousness, than having known it, to turn away from the holy commandment delivered to them. It has happened to them according to the true proverb, "A dog returns to its own vomit," and, "A sow, after washing, returns to wallowing in the mire.""
James 5:19-20 "My brethren, if any among you strays from the truth, and one turns him back, let him know that he who turns a sinner from the error of his way will save his soul from death, and will cover a multitude of sins."
Revelation 2:4-5 "'But I have this against you, that you have left your first love. 'Remember therefore from where you have fallen, and repent and do the deeds you did at first; or else I am coming to you, and will remove your lampstand out of its place-unless you repent."
Revelation 3:5 "'He who overcomes shall thus be clothed in white garments; and I will not erase his name from the book of life, and I will confess his name before My Father, and before His angels.
Revelation 3:16-17 'So because you are lukewarm, and neither hot nor cold, I will spit you out of My mouth. 'Because you say, "I am rich, and have become wealthy, and have need of nothing," and you do not know that you are wretched and miserable and poor and blind and naked"
Ezekiel 18:24-26 "But when a righteous man turns away from his righteousness, commits iniquity, and does according to all the abominations that a wicked man does, will he live? All his righteous deeds which he has done will not be remembered for his treachery which he has committed and his sin which he has committed; for them he will die. "Yet you say, 'The way of the Lord is not right.' Hear now, O house of Israel! Is My way not right? Is it not your ways that are not right? "When a righteous man turns away from his righteousness, commits iniquity, and dies because of it, for his iniquity which he has committed he will die."
