Although there are many Bible verses and passages that tell us that we have free will, the only one I really need is this one:
Revelation 3:5
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.
Obviously, one can have his or her name written in the Book of Life but then have it taken OUT.
...and it is all based upon whether or not you overcome SIN.
Not any different than what the Prophet Ezekiel said. God does not change. Jesus said when you have seen Me you have seen the Father.
Ezekiel 18:21
But if the wicked will
turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die.
Ezekiel 18:24
But when the righteous
turneth away
from his righteousness, and committeth iniquity, and doeth according to all the abominations that the wicked man doeth, shall he live? All his righteousness that he hath done shall not be mentioned: in his trespass that he hath trespassed, and in his sin that he hath sinned, in them shall he die.
Revelation 21:27
And there shall in no wise enter into it
any thing that defileth, neither whatsoever worketh
abomination, or
maketh a lie: but they which
are written in the Lamb's book of life.
Revelation 22:14-16
14 Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
15 For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
16 I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.
Only those who keep His Commandments will enter in.... no whoremongers (thou shalt not commit adultery), no murderers (thou shalt not kill), no idolaters (thou shalt not have any other gods before me thou shalt not worship any graven images), and not those who love and make a lie (though shalt not bear false witness against thy neighbor).
