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. iv. 8; what he is said to have received in the one place, he is said to have given in the other. 4. That he hath begun this work already by his Spirit in his followers; and therefore standeth engaged to see it perfected; for all his works are perfect works.
