4 We are indeed now very far removed in time from the first beginnings of Redemption; but what difference does this make when the benefits thereof are perennial and immortal? He who once bath restored human nature ruined by sin the same preserveth and will preserve it for ever. "He gave Himself a redemption for all" (1 Timothy II., 6)."In Christ all shall be made alive" (1 Corinthians XV., 22). "And of His Kingdom there shall be no end" (Luke I., 33). Hence by God's eternal decree the salvation of all men, both severally and collectively, depends upon Jesus Christ. Those who abandon Him become guilty by the very fact, in their blindness and folly, of their own ruin; whilst at the same time they do all that in them lies to bring about a violent reaction of mankind in the direction of that mass of evils and miseries from which the Redeemer in His mercy had freed them.
