Since the world’s creation, the apostle says, God’s unseen presence has been clearly visible (Rom. i. 20). Yet multitudes of men have always held false and corrupting views of the Divine nature. At this present time, in the full light of Christianity, men of high intellect and wide knowledge of nature are found proclaiming in the most positive terms that God, if He exists, is unknowable. This ignorance it is not for us to censure; every man must give account of himself to God. There may be in individual cases, amongst the enlightened deniers of God in our own days, causes of misunderstanding beyond the will, obstructing and darkening circumstances, on the ground of which in His merciful and wise judgement God may “overlook” that ignorance, even as He did the ignorance of earlier ages. But it is manifest that while this veil remains, those on whose heart it lies cannot partake in the life of God. Living in unbelief, they walk in darkness to the end, knowing not whither they go. The Gentile ignorance of God was attended, as St Paul saw it, with an _induration of heart_, of which it was at once the cause and the effect. There is a wilful stupidity, a studied misconstruction of God’s will, which has played a large part in the history of unbelief. The Israelitish people presented at this time a terrible example of such guilty callousness (Rom. xi. 7-10, 25). They professed a mighty zeal for God; but it was a passion for the deity of their partial and corrupt imagination, which turned to hatred of the true God and Father of men when He appeared in the person of His Son. Behind their pride of knowledge lay the ignorance of a hard and impenitent heart. In the case of the heathen, hardness of heart and religious ignorance plainly went together. The knowledge of God was not altogether wanting amongst them; He “left Himself not without witness,” as the apostle told them (Acts xiv. 17). Where there is, amid whatever darkness, a mind seeking after truth and right, some ray of light is given, some gleam of a better hope by which the soul may draw nigh to God,--coming whence or how perhaps none can tell. The gospel of Christ finds in every new land souls waiting for God’s salvation. Such a preparation for the Lord, in hearts touched and softened by the preventings of grace, its first messengers discovered everywhere,--a remnant in Israel and a great multitude amongst the heathen.
