Christ was manifested for the Elect of God only !2
Folks Unbelief is a Work of the devil, it began as his work from the beginning with Eve, whe he caused her to disbelieve God Gen 3:1-6
Now the serpent was more subtil than any beast of the field which the Lord God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?
2 And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:
3 But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.
4 And the serpent said unto the woman, Ye shall not surely die:
5 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
6 And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.
She obviously believed the Lie of the serpent over Gods command, when the serpent said to her "Ye shall not surely die"
She had already stated what God said Gen 3:3 so she believed the devil over God, which means Unbelief, Disobedience ! And man is imprsioned in that Unbelief Rom 11:32, unless Christ was manifested for them and took away their sins, in which case they must be set free from that prison of unbelief !
Now its a simple logical deduction from this, Unbelief is a work of the devil, and for one to remain in unbelief, they are under the power of the devil, and his power over them has not been defeated and they are operating from this spirit Eph 2:2
2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
But Glory to God that through Christ, if we be of the Elect, that power of the devil has been destroyed 1 Jn 3:8
He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
And because this is True, the Elect become Believers , Obedience 1 Pet 1:2 because of Him that was manifested for them 1 Pet 1:20-21
20 Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,
21 Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God.
If He was Manifested for Us to take away Our sins, we shall believe in the True God and Jesus Christ Jn 17:3
3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
To Know Him aright is to believe in Him Isa 43:10
Ye are my witnesses, saith the Lord, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me.
So if we teach that one Christ died for goes to hell in unbelief for their sins, we are teaching that Christ's Purpose for coming and being manifested was thwarted by the devil 1 Jn 3:5,8 ! And thats Blasphemy !
