For another Scriptural proof contra the Pelagian-BOD heresy, we have St. Paul justifying why God permits that many will not receive the Gospel and be damned for their sins:
"And if our gospel be also hid, it is hid to them that are lost, In whom the god of this world hath blinded the minds of unbelievers, that the light of the gospel of the glory of Christ, who is the image of God, should not shine unto them." 2 Cor. 4:3-4
