But well knowing that the Saviour teaches nothing in a merely human way, but teaches all things to His own with divine and mystic wisdom, we must not listen to His utterances carnally; but with due investigation and intelligence must search out and learn the meaning hidden in them. For even those things which seem to have been simplified to the disciples by the Lord Himself are found to require not less, even more, attention than what is expressed enigmatically, from the surpassing superabundance of wisdom in them. And whereas the things which are thought to have been explained by Him to those within— those called by Him the children of the kingdom— require still more consideration than the things which seemed to have been expressed simply, and respecting which therefore no questions were asked by those who heard them, but which, pertaining to the entire design of salvation, and to be contemplated with admirable and supercelestial depth of mind, we must not receive superficially with our ears, but with application of the mind to the very spirit of the Saviour, and the unuttered meaning of the declaration.
VI. For our Lord and Saviour was asked pleasantly a question most appropriate for Him—the Life respecting life, the Saviour respecting salvation, the Teacher respecting the chief doctrines taught, the Truth respecting the true immortality, the Word respecting the word of the Father, the Perfect respecting the perfect rest, the Immortal respecting the sure immortality. He was asked respecting those things on account of which He descended, which He inculcates, which He teaches, which He offers, in order to show the essence of the Gospel, that it is the gift of eternal life. For He foresaw as God, both what He would be asked, and what each one would answer Him. For who should do this more than the Prophet of prophets, and the Lord of every prophetic spirit? And having been called “good,” and taking the starting note from this first expression, He commences His teaching with this, turning the pupil to God, the good, and first and only dispenser of eternal life, which the Son, who received it of Him, gives to us.
VII. Wherefore the greatest and chiefest point of the instructions which relate to life must be implanted in the soul from the beginning—to know the eternal God, the giver of what is eternal, and by knowledge and comprehension to possess God, who is first, and highest, and one, and good. For this is the immutable and immoveable source and support of life, the knowledge of God, who really is, and who bestows the things which really are, that is, those which are eternal, from whom both being and the continuance of it are derived to other beings. For ignorance of Him is death; but the knowledge and appropriation of Him, and love and likeness to Him, are the only life.
VIII. He then who would live the true life is enjoined first to know Him “whom no one knows, except the Son reveal (Him).” Next is to be learned the greatness of the Saviour after Him, and the newness of grace; for, according to the apostle, “the law was given by Moses, grace and truth came by Jesus Christ;” and the gifts granted through a faithful servant are not equal to those bestowed by the true Son. If then the law of Moses had been sufficient to confer eternal life, it were to no purpose for the Saviour Himself to come and suffer for us, accomplishing the course of human life from His birth to His cross; and to no purpose for him who had done all the commandments of the law from his youth to fall on his knees and beg from another immortality. For he had not only fulfilled the law, but had begun to do so from his very earliest youth. For what is there great or pre-eminently illustrious in an old age which is unproductive of faults? But if one in juvenile frolicsomeness and the fire of youth shows a mature judgment older than his years, this is a champion admirable and distinguished, and hoary pre-eminently in mind.
But, nevertheless, this man being such, is perfectly persuaded that nothing is wanting to him as far as respects righteousness, but that he is entirely destitute of life. Wherefore he asks it from Him who alone is able to give it. And with reference to the law, he carries confidence; but the Son of God he addresses in supplication. He is transferred from faith to faith. As perilously tossing and occupying a dangerous anchorage in the law, he makes for the Saviour to find a haven.
IX. Jesus, accordingly, does not charge him with not having fulfilled all things out of the law, but loves him, and fondly welcomes his obedience in what he had learned; but says that he is not perfect as respects eternal life, inasmuch as he had not fulfilled what is perfect, and that he is a doer indeed of the law, but idle at the true life. Those things, indeed, are good. Who denies it? For “the commandment is holy,” as far as a sort of training with fear and preparatory discipline goes, leading as it did to the culmination of legislation and to grace. But Christ is the fulfilment “of the law for righteousness to every one that believes;” and not as a slave making slaves, but sons, and brethren, and fellow-heirs, who perform the Father's will.
X. “If you will be perfect.” Consequently he was not yet perfect. For nothing is more perfect than what is perfect. And divinely the expression “if you will” showed the self-determination of the soul holding converse with Him. For choice depended on the man as being free; but the gift on God as the Lord. And He gives to those who are willing and are exceedingly earnest, and ask, that so their salvation may become their own. For God compels not (for compulsion is repugnant to God), but supplies to those who seek, and bestows on those who ask, and opens to those who knock. If you will, then, if you really will, and art not deceiving yourself, acquire what you lack. One thing is lacking you—the one thing which abides, the good, that which is now above the law, which the law gives not, which the law contains not, which is the prerogative of those who live. He forsooth who had fulfilled all the demands of the law from his youth, and had gloried in what was magnificent, was not able to complete the whole with this one thing which was specially required by the Saviour, so as to receive the eternal life which he desired. But he departed displeased, vexed at the commandment of the life, on account of which he supplicated. For he did not truly wish life, as he averred, but aimed at the mere reputation of the good choice. And he was capable of busying himself about many things; but the one thing, the work of life, he was powerless, and disinclined, and unable to accomplish. Such also was what the Lord said to Martha, who was occupied with many things, and distracted and troubled with serving; while she blamed her sister, because, leaving serving, she set herself at His feet, devoting her time to learning: “You are troubled about many things, but Mary has chosen the good part, which shall not be taken away from her.” So also He bade him leave his busy life, and cleave to One and adhere to the grace of Him who offered everlasting life.
XI. What then was it which persuaded him to flight, and made him depart from the Master, from the entreaty, the hope, the life, previously pursued with ardour?— “Sell your possessions.” And what is this? He does not, as some conceive off-hand, bid him throw away the substance he possessed, and abandon his property; but bids him banish from his soul his notions about wealth, his excitement and morbid feeling about it, the anxieties, which are the thorns of existence, which choke the seed of life. For it is no great thing or desirable to be destitute of wealth, if without a special object—not except on account of life. For thus those who have nothing at all, but are destitute, and beggars for their daily bread, the poor dispersed on the streets, who know not God and God's righteousness, simply on account of their extreme want and destitution of subsistence, and lack even of the smallest things, were most blessed and most dear to God, and sole possessors of everlasting life.
