We know through scripture Christ died for all mankind so why would you make a claim that goes against scripture?
1 Peter 3:18 [Full Chapter]
For Christ also hath once suffered
for sins, the just
for the unjust, that he might bring us to God, and was put to death concerning the flesh, but was quickened by the spirit.
John 3 :
16 For God so loveth the world, that he hath given his only begotten Son, that whosoever believeth in him, should not perish, but have everlasting life.
17 For God sent not his Son into the world, that he should condemn the world, but that the world through him might be saved.
18 He that believeth in him, is not condemned: but he that believeth not, is condemned already, because he hath not believed in the Name of that only begotten Son of God.
19 And this is the condemnation, that that light came into the world, and men loved darkness rather than that light, because their deeds were evil.
20 For every man that evil doeth, hateth the light, neither cometh to light, lest his deeds should be reproved.
21 But he that doeth truth, cometh to the light, that his deeds might be made manifest, that they are wrought according to God.
