The Lord knows what we are, as so deeply, so awfully sunk in the Adam fall.
Adam was wise as well as upright; but with the fall both were gone as in a moment; for the same awful crash which broke to pieces his innocency wrecked and ruined his wisdom, and thus he became a fool as well as a sinner. This folly we inherit from him; for “foolishness is bound up in the heart of a child.” (Prov. 22:15) God, then, as perfectly acquainted with the folly of our mind, with our wretched ignorance and inability to find out the way of salvation, or to walk in it when found, has mercifully and graciously given to us One in the courts of bliss who shall be to us and for us far beyond all that we have lost, and has therefore made him our “wisdom.” “It hath pleased the Father that in him should all fulness dwell;” (Col. 1:19) and therefore a fullness of heavenly wisdom he communicates out of his fullness to his believing people. I do not like exactly to say that his wisdom is theirs by imputation, and yet there is a sense in which it may be called such.
Take for instance the figure of head and members. Is not our head, in a sense, wisdom for every member of the body?
Does it not bear the responsibility of every movement, so that all the wisdom or skill which any member possesses may be considered as being in the head?
Does not the eye guide the hands and feet?
Does not the ear hear for the whole body?
Does not the brain think and the tongue speak for every member?
Thus we see naturally that all our wisdom lies in our head, and the wisdom of our head is put to the account of all the members. So, spiritually, all our heavenly wisdom is in our covenant Head. The people of God see and feel their ignorance and folly; their inability to guide their own feet into the way of truth and peace. Their daily experience convinces them how easily they are entangled in the snares of sin and Satan; how dark their mind, how hard their heart, how carnal their frame, when the Lord does not communicate light, life, and power to their souls. To remedy then and overcome these miserable evils under which they groan and sigh, being burdened, Jesus Christ is of God made unto them wisdom; so that when the God and Father of the Lord Jesus Christ looks upon his dear Son in the courts of bliss, he views him as their representative head, and sees all the wisdom that they need stored up in his eternal fullness. Thus, as he does not impute to them their sins because of Christ’s righteousness, so he does not impute unto them their follies because of Christ’s wisdom. “Ye are wise in Christ,” says the apostle to the Corinthians (1 Cor. 4:10)–wise by your union with him. Now out of this wisdom which dwells in Christ without measure, he communicates to his people. They have none of their own. What they have is freely given to them liberally and bountifully, without stint and without upbraiding.
But it may be as well to glance at some of the effects of this wisdom as divinely communicated to the saints of God. To look unto Jesus by the eye of faith; to see him as the Son of God, “able to save to the uttermost all that come unto God by him;” and to view the treasures of love and grace which are stored up in his blood and righteousness, is also a part of this wisdom. To depart from all evil and seek all that is good; to obey the precepts as well as believe the promises; to walk tenderly, cautiously, and circumspectly in the fear of God; to read and pray and meditate; to commune with their own heart, and be ever seeking divine teaching, is a part also of this wisdom. In fact, this wisdom is indispensable for every right movement in heart, lip, and life; for every good word and work; for our conduct in the church and in the world; and for everybody becoming our holy profession. This the people of God deeply feel. Well do they know that not a single truth can they see aright except by seeing light in his light. Not a snare can they shun, or danger avoid, but by his warning voice or guiding hand; not a doctrine can they understand, not a promise believe, not a precept obey, except he who of God is made unto them wisdom, is pleased to communicate it to their heart. But, by looking to him, and receiving out of his fullness supplies of divine instruction, which he communicates to them through the word of his grace, as made life and spirit to their hearts, they are made wise unto salvation; and thus from their living and spiritual union with him, wisdom flows into their bosom out of his fullness, as in the figure of the vine, sap flows out of the stem into the branch. Thus, as he is their wisdom representatively in the courts of bliss, being their Counselor and Advocate who pleads their cause, so he is their wisdom efficiently, by the communication of this wisdom they have comes out of his fullness. And he is their wisdom also, as being the end and object of all the wisdom they possess or require, for the highest, greatest, and best of all wisdom is to know him and the power of his resurrection; to know experimentally the beauty and glory of his divine Person; the efficacy of his atoning blood and of his justifying righteousness; and, above all things, to know our happy and eternal interest in all that he is, in all that he has to the Church of God.
