The inculcation of discretion in the presentation of the truth may easily be exaggerated into a doctrine of reserve which is more Jesuitical than Christian. Even when guarded and limited, it may seem scarcely in harmony with the commission to preach the gospel to every creature, or with the sublime confidence that God's word finds something to appeal to in every heart, and has power to subdue the animal in every man. But the divergence is only apparent. The most expansive zeal is to be guided by prudence, and the most enthusiastic confidence in the universal power of the gospel does not take leave of common sense. There are people who will certainly be repelled, and perhaps stirred to furious antagonism to the gospel and its messengers, if they are not approached with discretion. It is bad to hide the treasure in a napkin; it is quite as bad to fling it down before some people without preparation. Jesus Himself locked His lips before Herod, although the curious ruler asked many questions; and we have sometimes to remember that there are people who 'will not hear the word,' and who must first 'be won without the word.' Heavy rains run off hard-baked earth. It must first be softened by a gentle drizzle. Luther once told this fable: 'The lion made a great feast, and he invited all the beasts, and among the rest, a sow. When all manner of costly dishes were set before the guests, the sow asked, "Have you no bran?" Even so, said he, we preachers set forth the most dainty dishes,--the forgiveness of sins, and the grace of God; but they turn up their snouts, and grub for guilders.'
This precept is one side of the truth. The other is the adaptation of the gospel to all men, and the obligation on us to preach it to all. We can only tell most men's disposition towards it by offering it to them, and we are not to be in a hurry to conclude that men are dogs and swine.
III. It may be a question whether, in verse 8, the emphasis is to be laid on 'every one' or on 'that asketh,' or, in other words, whether the saying is an assurance that the universal law will be followed in our case, or a statement of the universal condition without which no receiving is possible, and, least of all, the receiving of the gifts of the kingdom by its subjects. In either case, this verse gives the reason for the preceding exhortation. Then follows the tender illustration in which the dim-sighted love of earthly fathers is taken as a parable of the all-wise tenderness and desire to bestow which move the hand of the giving God. There is some resemblance between an Eastern loaf and a stone, and some between a fish and a serpent. However imperfect a father's love, he will neither be cruel enough to cheat his unsuspecting child with what looks like an answer to his wish but is useless or hurtful, nor foolish enough to make a mistake. All human relationships are in some measure marred by the faults of those who sustain them. What a solemn attestation of universal sinfulness is in these words of Christ's, and how calmly He separates Himself by His sinlessness from us! I do not know that there is anywhere a stronger scriptural proof of these two truths than this one incidental clause, 'ye, being evil.' I wonder whether the people who pit the Sermon on the Mount against evangelical Christianity are ready to take this part of it into their creeds. It is noteworthy, also, that the emphasis is laid, not on the earthly father's willingness, but on his knowing how to give good gifts. Our Lord seems to think that He need not assure us of the plain truth that of course our Father in heaven is willing, just because He is our Father, to give us all good; but He heartens us with the assurance that His love is wisdom, and that He cannot make any mistakes. There are no stones mingled with our bread, nor any serpents among the fish. He gives good, and nothing but good.
