8. Neither let them think, that the same measure is required of all. For more is required of some, by reason of their office and charge in the house of God, being called to teach and instruct others; and so more is required of such, as have larger capacities, and a better faculty of understanding than others, who naturally are but of a narrow reach, and of a shallow capacity. More also is required of such as live under plain, powerful, and lively ordinances, and under a more powerful and spiritual dispensation of the grace of God, than of others that want such advantages. So likewise, more is required of old Christians than of new beginners; old men, of much and long experience, should know more than such as are but babes in Christ and but of yesterday. 9. Let their desires run out after that knowledge, not which puffeth up,--for there is a knowledge which puffeth up, 1 Cor. viii. 1,--but which humbleth, and driveth the soul farther from itself and nearer to Christ. 10. They should carefully distinguish betwixt the gift of knowledge and the grace of knowledge: That ordinarily puffeth up, this humbleth; that bringeth not the soul to Jesus, this doth; that is but a form, Rom. ii. 20, and doth not retain God, Rom. i. 28, this is a real thing, laying hold on God and holding him fast, having the fear of the Lord for its principle, for this "fear of the Lord is the beginning of wisdom," Job. xxviii. 28. Psalm cxi. 10. Prov. i. 7, and ix. 10.; that lieth most in the head, and venteth most in discourses, words, yea, and sometimes vanisheth into vain notions, but this goeth down to the heart, and lodgeth there and appeareth in the man's walk and conversation; as these two would be distinguished, so the one would not be measured by the other. 11. When they do not profit indeed, let them beware of quarrelling with Christ, or of blaming him in any manner of way; but let them lay the blame of their shortcoming on themselves, for not making more use of him by faith and single dependence upon him. It is true, none will be so bold as in words to quarrel with or blame him; yet the heart is deceitful and tacitly may raise and foment such thoughts of him and his dispensations, as can pass under no other notion than a quarrelling with him. Now these would be guarded against. 12. Beware of urging for, or expecting immediate revelation, or extraordinary manifestations. For we should not tempt the Lord, nor set limits to him, neither should we prescribe means and ways to him,--we must be satisfied with the ordinary means which he hath appointed, and wait at wisdom's doors, with our ears nailed to his posts. 13. Whatever point of truth they learn, or whatever measure of knowledge they get, they would do well to give that back again to Christ, to keep for them against a time of need; and wait on him for grace to improve it for his glory.
