Featured Calvinism and Aminianism and their influence on Adventist belief

Yes, but Christ will judge at the end, not man. And many Christians are told its ok to worship idols, and follow false traditions, etc.. and they think they are saved and are following Christ when in reality they are going down another path.

 

The Jews thought the same thing and yet they were following those who were not sent by God, who were deceiving them much as is happening today:

Jeremiah 29:8-11 King James Version (KJV)
8 For thus saith the Lord of hosts, the God of Israel; Let not your prophets and your diviners, that be in the midst of you, deceive you, neither hearken to your dreams which ye cause to be dreamed.
9 For they prophesy falsely unto you in my name: I have not sent them, saith the Lord.
10 For thus saith the Lord, That after seventy years be accomplished at Babylon I will visit you, and perform my good word toward you, in causing you to return to this place.
11 For I know the thoughts that I think toward you, saith the Lord, thoughts of peace, and not of evil, to give you an expected end.

Now we see that God sees the future so He knows who will be lost and those saves, but knowing does not mean He is unjust and takes away His offer of eternal life to those who will be lost, look at Judas.

Romans 8:28-31 King James Version (KJV)
28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
29 For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
30 Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
31 What shall we then say to these things? If God be for us, who can be against us?

Even though God has known from the beginning, He has laid out before people clear warnings against sin, and has provided them with all the necessary means for avoiding it. But God cannot interfere with man’s freedom of choice without depriving him of his freewill and making him the same as a robot.

 

That is the key, even if Judas would not be saved, Christ still accepted Him, knowing what was to come.

John 6:68-71 King James Version (KJV)
68 Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life.
69 And we believe and are sure that thou art that Christ, the Son of the living God.
70 Jesus answered them, Have not I chosen you twelve, and one of you is a devil?
71 He spake of Judas Iscariot the son of Simon: for he it was that should betray him, being one of the twelve.

 

And yet Moses asked to be blotted out of it if God could not forgive the people:

Exodus 32:32 King James Version (KJV)
32 Yet now, if thou wilt forgive their sin--; and if not, blot me, I pray thee, out of thy book which thou hast written.

And we see it in the NT...
Revelation 3:5 King James Version (KJV)
5 He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.

 

Christ gives the offer to all, we are free to choose. I came across this study on Judas which can be applied even to Christians...

"Luke tells us that Jesus called “the twelve” together—that included Judas—and “gave them power and authority over all demons and to cure diseases, and he sent them out to proclaim the kingdom of God and to heal” (Luke 9:1–2).

Judas Iscariot was a gospel preacher! He was given the gift of healing, and he exercised authority over demons. Active involvement in ministry is a good and wonderful thing; but it is not, in itself, a guarantee of spiritual life or health."...4 Things We Can Learn from Judas

 

Revelation 20:12
And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.

 

And yet you can be taken out...
Revelation 22:19
And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.
