No man, when he hath lighted a candle, &c. See on Matthew 5:15; and Mark 4:21. Nothing is secret, &c. See on Matthew 10:26. Take heed, therefore, how ye hear. In Mark 4:24, it is, Take heed what you hear. As it is the indispensable duty of all ministers of the Word to take heed what they preach, 1st, That their doctrine be true, that they may not deceive their hearers. 2d, That it be important, that they may not trifle with them: and, 3d, That it be suitable to their state and character; that they rightly divide the word of truth, and give to every description of hearers their portion of meat in due season; so it concerns all hearers to take heed what they hear. They must not take it for granted that what they hear is true, important, and suited to their state and character: but must bring it to the test of the Holy Scriptures, and examine it thereby; and for that purpose, must endeavour to make themselves well acquainted with the Scriptures: and if they find that, according to the divine oracles, the doctrine which they hear answers the above description, they must so take heed what they hear, as to attend to, and consider it well, that they may thoroughly understand and lay it to heart, and that it may have its designed effect upon their spirit and conduct.
But, according to Luke here, our Lord's caution, inferred from the preceding parable, implied another thing equally important, Take heed how ye hear 1st, That you do not hear so inattentively, and in such a prayerless state of mind, as not to understand, nor afterward meditate on what your hear, and so receive the seed as by the way-side. See on Matthew 13:19. 2d, That having heard, and understood in a measure what you heard, and being affected thereby, you do not rest in any ineffectual and transient impressions made on your mind, and therefore be offended and fall away in time of trial and temptation; but that the truth may take deep root in your mind, and that you may have root in yourself. See on Matthew 13:20-21. Take heed, 3d, That you guard against the cares of the world, the love of deceitful riches, the vain pleasures of life, and desires after other things; those pernicious weeds, which in so many choke the springing blade, or forming ear, so that no fruit is brought forth to perfection. See on Matthew 13:22. But hear, 1st, In simplicity of intention, with a single eye to the glory of God and your own salvation, present and eternal. 2d, In sincerity of heart, truly and earnestly desiring to discover and put away every error and every sin, and to know and do the whole will of God. 3d, In humility, conscious that you are unworthy to know the great and important things revealed in the gospel, the will of God, and the way of salvation from such great misery to such great happiness, unworthy that God should speak to you by his Son, and his inspired prophets, apostles, and evangelists. 4th, With reverence, remembering it is God's word, and you are in God's presence and under God's eye. 5th, With seriousness, persuaded the truth you hear is no light matter, but for your life, your better and everlasting life. Would you not hear with seriousness the advice of a skilful physician respecting your health, or of a lawyer concerning your property? And will you not hear with equal, nay, with greater seriousness what concerns you infinitely more? 6th, With deep attention: let no sentence, or even word, that is uttered escape you, and fail not afterward seriously to consider what you have heard, and to examine yourself thereby. 7th, With prayer, while hearing, and before and after you hear, for the spirit of wisdom and revelation, Ephesians 1:17: persuaded the things of God knoweth no man but by the Spirit of God, 2Co 2:11; 2 Corinthians 2:14. 8th, Hear with faith, firmly believing the certainty and importance of what is taught you from the oracles of God, always remembering the word preached does not profit those who hear it, in whom it is not mixed with faith, Hebrews 4:2. 9th, In love to the truth, though searching and cutting, though disagreeable to your mind, like a bitter medicine to your taste, or giving pain, like a lance which opens an imposthume. 10th, With meekness, with a calm, unruffled, peaceful mind, that what you hear may prove an ingrafted word able to save your soul, James 1:21. Above all, 11th, Hear with a fixed resolution, formed in the strength of grace, to be a doer of the word, and not a hearer only, to practise all you hear as far as you see it to be agreeable to the word and will of God. For whosoever hath, to him shall be given. See note on Matthew 13:12; and Mark 4:25.
