1. _What is in the heart of such a man?_ See Gen. vi. 5. This is the mint that is always at work; sin worketh in the heart all day, and playeth in the fancy all night; there is no truce in this warfare. 2. _What cometh out of such a heart?_ See Mark vii. 21, 22. 3. _In what sense is it little worth?_ (1.) As to acceptation with God. (2.) As to the benefit and profiting of others. Observe--1. _That the heart of the wicked is spoken of in the softest terms._ Elsewhere it is said to be deceitful above all things and desperately wicked (Jer. xvii. 9). And this teaches us that it is not enough to do no harm by our speech, but it must benefit others. 2. _Till we make conscience of our thoughts, we cannot well order our words._ 3. _Familiar converse with those whose hearts are nothing worth, will tend to our hurt._ 4. _Be sure that you get another heart._ For though it be not in our power to make ourselves a new heart, it is our duty to get it.--_Manton._ Verse 21. A great housekeeper he is, hath his doors ever open, and, though himself be poor, yet he "maketh many rich" (2 Cor. iv. 10). He well knows that to this end God put "honey and milk under his tongue" (Cant. iv. 11), that he might look to this spiritual lip-feeding. To this end hath he communicated to him those "rivers of water" (John vii. 38) that they may flow from him to quench that world of wickedness, that, being set on fire of hell would set on fire the whole course of nature (Jas. iii. 6). They are "_empty_ vines that bear fruit to themselves" (Hosea x. 1).--_Trapp._ This bread of life which the disciples distribute is not like common bread. The more you give of it to the needy, the more remains for your own use. It is the bread which Jesus blesses in the wilderness--the bread from heaven, which Jesus is; and when from His hand, and at His bidding, you have fed three thousand on five loaves, you will have more bread remaining in your baskets than the stock you begin with. . . . Fools, so far from being helpful to other, have nothing for themselves. They have taken no oil in their vessels, and the flames of their lamp dies out.--_Arnot._ _MAIN HOMILETICS OF VERSE_ 22. The Source of True Riches.
