Another truth implied in the Spirit's conviction of the world is that present salvation and eternal life depend solely on faith in Christ for which there can be no substitute. By this declaration the pious, God-fearing pagan living up to his best light is not excluded from salvation. He evinces that he has the spirit of faith and the purpose of righteousness which are accepted in the involuntary absence of a knowledge of the historic Christ. He has engraven on his own character, through co-operation with the universal activity of the Holy Spirit, the imperfect outlines of the image of Christ, styled by Joseph Cook "the essential Christ." When the apostles demonstrated to the conscience of the Jews that there was salvation in no other name, not even in Abraham their father nor in Moses their lawgiver, they were convicted of the most stupendous crime possible, but not beyond the forgiving grace of their disowned and crucified Messiah. Great as was their first crime of murdering their King, their second offense of rejecting His claims did not place them individually beyond His pardoning mercy, if they would repent and believe, although it sealed their national doom. Their unbelief vitiated all their fancied righteousness sought from the law and rendered it detestable and all their sacrifices abominable to the searcher of hearts. They were preeminently guilty of unbelief. The temporal consequences to their nation manifestly confirm the assertion that it was the most heinous of all sins.
