Their principles of thought were pure, but they felt that there existed a purity which was beyond their reach; their standard of conduct was high, but they were inwardly conscious that it ought to be higher. On that golden "ladder of sunbeams" which rises from earth to the angel-guarded battlements of heaven, they had ascended a few timid steps, but above and beyond they could see a glory to which it was not given them to rise. Hence it has often been said, and justly, that the men were greater than their system; and such, so far as Magianism was concerned, may well have been the case with the loftier minds of Bactria and Persia. But it can never be pretended that the Christian is greater than Christianity. Let him be ever so holy in his living, ever so exalted in his aspirations, he will not seek for something _beyond_ and _out of_ Christianity, because he feels and knows that he cannot exhaust all its capabilities; that it soars far higher than he can ever soar. It has truths which the profoundest psychologist cannot fathom; it opens up visions which the boldest imagination cannot comprehend; it contains a wealth of emotion and sympathy which the most passionate soul can never exhaust. After we have said and done all we can, after we have mastered all that has been said and done by other men, we still find in the life and character of CHRIST that which may well engage, and yet never weary our attention. And here we touch upon a feature which no human system of religion or morality has ever matched. Strip the Zendavesta, if you will, of all its later and less worthy adjuncts, and yet it cannot, any more than the Rig-Veda, present us with the divine beauty of the Man of Sorrows. But this it is which fills, soothes, blesses, inspires the aching, restless, craving human heart. When it can no longer satisfy itself with the cold moralities of philosophy, when it pines for a deeper and a warmer life, when it is weary with problems which it cannot solve, and disappointed in hopes which it has seen fade away like dreams of the night, it turns to the Cross and is comforted. The mysteries which perplexed it vanish in the light that emanates from the Divine history of the SON of GOD. The awe with which it regards the passionless abstraction of a great First Cause, a supreme entity of Power and Wisdom without Love, passes into reverent admiration and joyous thanksgiving when it looks up into the face of the Good Shepherd, and reposes in the shadow of the Vine, and learns how that He Who was with the FATHER before the beginning, has suffered even as we suffer, has borne the heavy burden of the flesh even as we have borne it, and now sits on the right hand of GOD,--not an idea, not a principle, not a Spirit, but a PERSON, bidding all who believe to come unto Him and be at rest.
