Because Christ also suffered for sins once, the righteous for the unrighteous, that he might bring you to God; being put to death in the flesh, but made alive in the spirit;
The righteous for the unrighteous ...  Let it be strictly observed that Peter in this does not say, "That he might bring God to us," but "that he might bring us to God."  There was nothing in the atonement that was designed to change God in any manner; for it was men who needed to be changed.  The separation between God and man "is one-sided."[28] The suffering of Christ was not to satisfy God but for the purpose of getting the attention of rebellious men.  God already loved humanity before the atonement was even possible.
