If Christ put away all the sins of the whole word using your definition of "whole word" (that being every single person in existence without exception), then why is anyone cast into everlasting fire?
The law requires a "Death" for sin, if Jesus had not fulfilled the law, (paid the fine)

Jesus took away the law than condemned "ALL" of us, that we "MIGHT BE" saved, his death didn't take away our sins, for that to ocurr, we have to make the same sacrifice Jesus made,
Crucify the flesh by confessing/repenting of the sins of the flesh, and allowing the "Spirit" to take control instead of obeying the "lust of the flesh".

Ro 8:13 For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
Col 3:9 Lie not one to another, seeing that ye have put off the old man with his deeds;
10 And have put on the new man, which is renewed in knowledge after the image of him that created him:
NE is satisfied apart from faith -- not even once.
