Absolutely by grace are you saved through faith and this not of yourselves it is the gift of God lest anyone should boast.
Not having an understanding of the scriptures and the power of God, corrupted men add all sorts of diverse and strange doctrines.
Our ending up saved all begins with God's predestination choosing of us, working all things according to the council of His will, which is His calling of us to be saved according to His favoring mercy and grace, which so many reject. And you can post scripture after scripture and it is twisted or ignored or they say just keep drinking the kool-aid, which is a veiled judgement of death being pronounced by them on those who do know God and the power of His salvation to save us who believe.
Jesus word's they ignore, so obvious they add to and take away from what Christ says, meaning they are under God's curse.
Jesus says He plainly tells these Jews who are supposedly God's people the truth and they do not believe.
The reason they do not believe is they are not of God, so they do not listen-hearken to His words.
They are not of God because they are not born again by the Holy Spirit, they are spiritually dead in sin and do not recognize the Lord Jesus Christ because they are flesh and not spiritually alive. Flesh is flesh and spirit is spirit and you must be born again in the Spirit of God to enter- see the kingdom of God.
The inspiration of their minds is devilish wisdom only regarding the genuine Jesus being the way, the truth and the light.
The Shepherd Knows His Sheep
22 Now it was the Feast of Dedication in Jerusalem, and it was winter.
23 And Jesus walked in the temple, in Solomon’s porch.
24 Then the Jews surrounded Him and said to Him, “How long do You keep us in doubt? If You are the Christ, tell us plainly.”
25 Jesus answered them, “I told you, and you do not believe. The works that I do in My Father’s name, they bear witness of Me.
26 But you do not believe, because you are not of My sheep, as I said to you.
27 My sheep hear My voice, and I know them, and they follow Me.
28 And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand.
29 My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Father’s hand.
30 I and My Father are one.”
My Father, who has given them to Me!, see they do not believe Christ regarding this truth which Paul here in Romans 8 gives detailed explanation. They prefer anything but this truth of His calling for those whom He predestined to be Christians which results in our glorification.
The reason they are His sheep is the Father has given them to Christ. Christ additionally confirms this in John 17 where Christ says He has power over all flesh to give eternal life to as many as God has given to Christ as believers in Christ.
17 Jesus spoke these words, lifted up His eyes to heaven, and said: “Father, the hour has come. Glorify Your Son, that Your Son also may glorify You,
2 as You have given Him authority over all flesh, that He should give eternal life to as many as You have given Him.
3 And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.
Romans 8
28 And we know that all things work together for good to those who love God, to those who are the called according to His purpose. 29 For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren. 30 Moreover whom He predestined, these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.
God’s Everlasting Love
31 What then shall we say to these things? If God is for us, who can be against us? 32 He who did not spare His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things? 33 Who shall bring a charge against God’s elect? It is God who justifies. 34 Who is he who condemns? It isChrist who died, and furthermore is also risen, who is even at the right hand of God, who also makes intercession for us. 35 Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? 36 As it is written:
“For Your sake we are killed all day long;
We are accounted as sheep for the slaughter.”
37 Yet in all these things we are more than conquerors through Him who loved us. 38 For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, 39 nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord.
