_The heart_, in the language of the Bible, never denotes the emotional nature by itself. The antithesis of “heart and head,” the divorce of feeling and understanding in our modern speech is foreign to Scripture. The heart is our interior, conscious self--thought, feeling, will in their personal unity. It needs the whole Christ to fill and rule the whole heart,--a Christ who is the Lord of the intellect, the Light of the reason, no less than the Master of the feelings and desires. The difference in significance between “Christ” or “Christ Jesus” and “the Christ” in such a sentence as this, is not unlike the difference between “Queen Victoria” and “the Queen.” The latter phrase brings Her Majesty before us in the grandeur and splendour of her Queenship. We think of her vast dominion, of her line of royal and famous ancestry, of her beneficent and memorable reign. So, to know the Christ is to apprehend Him in the height of His Godhead, in the breadth of His humanity, in the plenitude of His nature and His powers. And this is the object to which the teaching and the prayers of St Paul for the Churches at the present time are directed. Understanding in this larger sense the indwelling of the Christ for which he prays, we see how naturally his supplication expands into the “height and depth” of the ensuing verse. But however large the mental conception of Christ that St Paul desires to impart to us, it is to be grasped “through faith.” All real understanding and appropriation of Christ, the simplest and the most advanced, come by this channel,--through the faith of the heart in which knowledge, will and feeling blend in that one act of trustful apprehension of the truth concerning Jesus Christ by which the soul commits itself to Him.
