This is a staggeringly crass interpretation. Did you notice that in no place does scripture say Adam and Eve had no freewill either, or did that slip by your mental gymnastics?
The whole of scripture demonstrates the exercise of freewill, either by God, man, or Satan. Yet you read the genesis account, but conclude the opposite when there is no mention that Adam has no freewill.
Gen1v15Then the Lord God took the man and put him in the garden of Eden to tend and keep it. 16And the Lord God commanded the man, saying, “Of every tree of the garden you may freely eat; 17but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die.”
God instructs Adam not to eat of the Tree of Knowledge, nevertheless he does eat it. That demonstrates Adam had freewill, and he could have eaten of the Tree of Life instead of death.
The deception lies with you not me.
So how come sin still controls so many believer's lives if they have no freewill to disobey?
Likewise yourself.
Again, this has absolutely nothing to do with the disciples becoming believers. Jesus is simply choosing Jewish believers to become disciples. That's why he asks whether they would desert him as others had already done.
John6v66From that time many of His disciples went back and walked with Him no more. 67Then Jesus said to the twelve, “Do you also want to go away?”
Why would Jesus ask this if the disciples had no freewill?
68But Simon Peter answered Him, “Lord, to whom shall we go? You have the words of eternal life. 69Also we have come to believe and know that You are the Christ, the Son of the living God.”
Peter makes it clear that he was choosing to stay. Again, an exercise of freewill.
70Jesus answered them, “Did I not choose you, the twelve, and one of you is a devil?” 71He spoke of Judas Iscariot, the son of Simon, for it was he who would betray Him, being one of the twelve.
Again, a reference to Jesus choosing Godly disciples. Judas is mentioned separately because he was unregenerate, demonstrating that all the others were considered to be believers.
Absolutely nothing you have presented shows man has no freewill when it comes to salvation. In contrast, scripture is filled with challenges for man to make that choice of turning to God.
None of these verses indicate what you are saying.
You argue from silence for your imagined support for free will.
The moment that you said "The whole of scripture demonstrates the exercise of freewill, either by God, man, or Satan", you added to the Word of God for there is no place in scripture that states that mankind has a free-will. Adding to the Word of God carries a severe and deadly punishment (Revelation 22:18-19).
REGARDING GENESIS
By the way, in your self will (2 Peter 2:9-10), you miscited the verses of Genesis. It's Genesis chapter 2.
God issued prophecy about man eating the fruit (Genesis 2:17)
AT the time God commanded the man, Adam, not to eat of the tree
AND the consequence of disobedience is declared - that is that death of the man would result in eating from the tree
YET a command does not convey ability
BUT the language contains a prophetic construct indicating assurance of occurrence - "for in the day that you eat" - the "for" is promissory
NOT a conditional logic construct such as "if in the day that you eat"
IN fact, the English word "for" is translated from the Hebrew word ki (Strong's Hebrew: 3588. (ki) -- that, for, when)
AND the Hebrew word ki contains the meanings of these English words "that", "for", "when"
THEREFORE the word "when" fits where the word "for" resides in Genesis 2:17
THUS the phrase "when in the day that you eat" is an accurate translation for Genesis 2:17
SO this confirms the promissory nature, the prophecy of man eating the fruit, with the word "for"/"when" in Genesis 2:17
REGARDING JOHN 6:66-70
It is written that many, but not all, the disciples departed, so not only to the 12 apostles remain, but also Matthias and Joesph remain as identified by Luke (Acts 1:13, Acts 1:21-23).
The passage does not indicate that only the apostles are chosen by Jesus.
REGARDING FREEWILL
There is no place in the New Testament that indicates man has a free will.
Every time you write that man has a freewill, you oppose that which is written.
REGARDING THE WORD OF GOD
People of the sin nature cannot understand spiritual things of God (1 Corinthians 2:14).
There is no level that a person can choose Lord Jesus because He said "you did not choose Me, but I chose you" (John 15:16) - Jesus, being God, did not provide any exception for choosing toward Jesus. Lord Jesus speaks to all believers in all time because He also said "I do not ask on behalf of these alone, but for those also who believe in Me through their word" (John 17:20)! All these words of Jesus are at the same supper! All glory is God's! With man, salvation is impossible (Matthew 19:25-26)! All glory in the salvation of man is God's (John 15:5, Isaiah 42:8)!
