Chapter 48

HOW TO MAKE USE OF CHRIST AS THE TRUTH, FOR GROWTH IN KNOWLEDGE.

It is a commanded duty, that we grow in the knowledge of Jesus Christ, 2 Pet. iii. 18; and the knowledge of him being life eternal, John xvii. 3, and our measure of knowledge of him here being but imperfect, for we know but in part, it cannot but be an useful duty, and a desirable thing, to be growing in this knowledge. This is to walk worthy of the Lord unto all pleasing, to be increasing in the knowledge of God, Col. i. 10. Knowledge must be added to virtue; and it layeth a ground for other Christian virtues, 2 Pet. i. 5, 6. In this knowledge we must not be barren, 2 Pet. i. 2. And this being so necessary, so desirable, so useful, and so advantageous a grace, the believer cannot but desire to have more and more of it, especially seeing it is a part of the image of God, Col. iii. 10.

Now it is the truth that must teach them here, first and last. "The light of the knowledge of the glory of God must be had in the face of Jesus Christ," 2 Cor. iv. 6. The question therefore is, how we should make use of Jesus Christ for this end, that we may attain to more of this excellent knowledge.

_First._ It is good to live in the constant conviction of a necessity of his teaching us, and this taketh in those particulars:

1. That we should be conscious of our ignorance, even when we know most, or think we know most, remembering that the best knoweth but in part, 1 Cor. xiii. 9. The more true knowledge we attain to, the more will we see and be convinced of our ignorance; because the more we know, the more will we discover of the vastness and incomprehensibility of that object, which is proposed to our knowledge.

2. That we should remember, how deceitful our hearts are; and how ready they are to sit down upon a shadow of knowledge, even where we know nothing as we ought to know, 1 Cor. viii. 2; and this will keep us jealous and watchful.

3. And to help forward our jealousy of our own hearts and watchfulness, we should remember that our hearts naturally are averse from any true and saving knowledge; whatever desire there be naturally after knowledge of hidden things out of curiosity; and of things natural; or of things spiritual, as natural, for the perfection of nature, as might be pretended, whereby in effect those that increase knowledge, increase sorrow, Eccl. i. 18. Yet there is no inclination after spiritual and saving knowledge, in us naturally, but an aversion of heart therefrom.

4. That we should study and know the absolute necessity of this knowledge. How necessary it is for our Christian communion with God, and Christian walk with others; how necessary for our right improving of dispensations, general and particular; what a noble ornament of a Christian it is, and a necessary piece of the image of God, which we have lost.

_Secondly._ Upon these grounds mentioned, we would also be convinced of this:

1. That of ourselves, and by all our natural parts, endowments, quickness and sagacity, we cannot attain to this saving knowledge, which is a special and saving grace, and so must be wrought in the soul by a divine hand, even the mighty power of God. By our private study and reading, we may attain to a literal, heady, and speculative knowledge, that will puff us up, 1 Cor. viii. 1; but thereby shall we never attain to this knowledge, which is spiritual, hearty, and practical, and so saving, we must have the anointing here, which teacheth us all things, 1 John ii. 27. And of this we should be persuaded, that we may look to a higher hand for light and instruction.

_Thirdly._ There should be an eyeing of Christ's furniture and fitness for this work of teaching of us, to wit,

1. An eyeing of him as the substantial wisdom of the Father, Prov. viii.

2. An eyeing of him, as one come out of the bosom of the Father, John i. 18; and so sufficiently enabled to acquaint us with the mysteries of God for salvation.

3. An eyeing of him as Mediator, fully endued with all necessaries for this piece of his work, and so having received the Spirit without measure, for this end, John iii. 34; and as having hid in him all the treasures of wisdom and knowledge, Col. ii. 3; and as having all fullness dwelling in him, Col. i. 19; and also Isa. xi. 2; lxi. 1,2.

4. An eyeing of him, as having power to send the Spirit, that anointing that teacheth us all things, "and is truth and is no lie," 1 John ii. 20-27; not only by way of intercession and entreaty, begging it of the Father, John xv. 16, 17; but also authoritatively, as conjunct with the Father. The Father sendeth him in Christ's name, John xiv. 26; and Christ sendeth him from the Father, John xv. 26; and this Spirit of truth which guideth into all truth, shall receive of Christ's, and shew it unto us, John xvi. 13-15.

_Fourthly,_ There should be an eyeing of Christ's readiness, willingness, and engagement to help in this case; and this will encourage the soul to go forward. And for this cause we would remember those things:

1. That he standeth obliged to help us with instruction, by virtue of his office, as a prophet, a witness, a leader, and a commander, Isa. l v. 4.

2. That he is commissioned of the Father for this end, and so is the Father's servant; and is given for "a light to the Gentiles," Isa. xlii. 6; xlix. 6; and the Father is said to speak by him, or in him, Heb. i. 1.

3. That he received his gifts and qualifications for this end and purpose, that he might give out and dispense to his members according to their necessity; as is clear from Psalm lxviii. 18, compared with Eph.
