Our Lord here encourages His disciples to count on the goodness of their Father for every want consistent with His will.
" Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened to you. For every one that asketh receiveth, and he that seeketh findeth; and to him that knocketh it shall be opened. Or what man is there of you, who, if his son shall ask of him for a loaf, will give him a stone; and if he ask for a fish, will give him a serpent? If therefore ye, being wicked, know to give good gifts to your children, how much rather shall your Father that is in the heavens give good things to those that ask him? Therefore all things whatsoever ye desire that men should do to you, thus do ye also to them; for this is the law and the prophets " (Matt. 7:7-127Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: 8For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. 9Or what man is there of you, whom if his son ask bread, will he give him a stone? 10Or if he ask a fish, will he give him a serpent? 11If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him? 12Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets. (Matthew 7:7‑12)).
It is not a shiner needing life and forgiveness of his sins, but saints directed to appeal to God and assured of their Father's answer of love, whatever their wants be. The Lord had already taught them to pray in chap. 6 as with alms and fasting, parts of saintly righteousness and due to His name and glory. Here He enforces it as the way in which all they need from above is to be given them. Hence perseverance and earnestness are incumbent. Asking will ensure receiving, yea to every one that asks; seeking will not be fruitless but shall find; and to the still more importunate the door will be opened, which is but shut to exercise faith. For there may be a matter of importance for the applicant to learn before the request can be granted, as with the Syrophenician woman, so earnest in supplicating the Lord to have pity on her, whose daughter was grievously possessed by a demon. Yet at first the Lord answered her not a word. She pleaded like a lost sheep of Israel's house; whereas she was a Greek, and had no right of promise with the Messiah; indeed she was a Canaanite, and thus under the curse. But when she drops His title as Son of David, and gathered from His answer to the disciples wherein her mistake lay, she did Him homage, saying, Lord, help me. On this He speaks out, It is not good to take the bread of the children, and cast it to the whelps. This did help her soul, for it led her to the secret of sovereign grace on which she at once threw herself, saying, Yea, Lord; for even the whelps eat of the crumbs which fall from the table of their masters. Then Jesus answering said to her, O woman, great is thy faith; be it done to thee as thou wilt. The door opened to her knock. She was deepened and cleared in her faith, as her daughter was healed from that hour.
The Lord also encourages His disciples through the affection which is implanted in a parent's heart. If their Father makes His sun rise on evil and good, and sends rain on just and unjust, how does He feel toward His sons? His love surely goes out to them in every request that is for their good, and withholds only what their foolishness asked that must do them harm. Hence He says, Or what man of you, whom his son shall ask for a loaf, will he give him a stone? and if he asks for a fish, will he give him a serpent? Who would not repudiate such mockery of a. son's hunger? Thence He draws the conclusive words for their hearts, If ye then, being wicked, know how to give good gifts to your children, how much more shall your Father that is in the heavens give good things to those that ask Him?
The last verse goes into that which becomes the disciple with men, and lays down the simple but evidently sound principle, to do to others as we would have others do to us; and this too on no ground of human rights or natural benevolence, but of consistency with God's revealed will. "All things therefore whatsoever ye would that men should do to you, thus also do ye to them; for this is the law and the prophets."
Now let me ask you, dear reader, if you have not by faith the Son of God as your Savior, are you not conscious that these words are altogether beyond you? What is your state then now, and what must the end be? I call on you in the Lord's name that you perish not in your sins. The same Lord, who thus cheers His disciples and bids them ask freely, warns you that he who disbelieves (who is unsubject to) the Son, shall not see life, but the wrath of God abides upon him. Go to God as you are, a poor sinner, in the Savior's name, and own your ruin and His grace, that you may be saved, and know it to your exceeding and everlasting joy; and then serve Him as your Lord, awaiting Him from heaven, for He is coming.
