How long shall we continue in this manner, our intellect reduced to futility, failing to make the spirit of the Gospel our own, not knowing what it means to live according to our conscience, making no serious effort to keep it pure? Lacking real knowledge, we still trust solely in the apparent righteousness of our outward way of life, and so lead ourselves astray, trying to please men, pursuing the glory, honour and praise which they offer. But the Judge who cannot be deceived will certainly come, and 'will bring to light the things now hidden in darkness, and reveal the purposes of hearts' (I Cor. 4-: 5). He neither respects the wealthy nor pities the poor, but strips away the outward appearance and reveals the truth hidden within. In the presence of the angels and before His own Father, He crowns those who have truly pursued the spiritual way and lived according to their conscience; and in the presence of the heavenly Church of the saints and of all the celestial hosts, He exposes those who possessed merely an outward pretence of devotion, which they displayed to men, vainly relying on it and deceiving themselves; and He banishes them in shame to outer darkness.
