7:11 If ye then, being evil. Men who have the natural affection of parents, even though sinful men, will not do such things. Whoever believes that the term Father, as applied to God, is more than a figure of speech, must believe in prayer.
Give good gifts. Lu 11:13, in the parallel passage, says, instead of good gifts, the Holy Spirit, as though this is heaven's greatest blessing.
7:11 To them that ask him - But on this condition, that ye follow the example of his goodness, by doing to all as ye would they should do to you. For this is the law and the prophets - This is the sum of all, exactly answering Mt 5:17. The whole is comprised in one word, Imitate the God of love. Thus far proceeds the doctrinal part of the sermon. In the next verse begins the exhortation to practise it.
7:7-11 Prayer is the appointed means for obtaining what we need. Pray; pray often; make a business of prayer, and be serious and earnest in it. Ask, as a beggar asks alms. Ask, as a traveller asks the way. Seek, as for a thing of value that we have lost; or as the merchantman that seeks goodly pearls. Knock, as he that desires to enter into the house knocks at the door. Sin has shut and barred the door against us; by prayer we knock. Whatever you pray for, according to the promise, shall be given you, if God see it fit for you, and what would you have more? This is made to apply to all that pray aright; every one that asketh receiveth, whether Jew or Gentile, young or old, rich or poor, high or low, master or servant, learned or unlearned, all are alike welcome to the throne of grace, if they come in faith. It is explained by a comparison taken from earthly parents, and their readiness to give their children what they ask. Parents are often foolishly fond, but God is all-wise; he knows what we need, what we desire, and what is fit for us. Let us never suppose our heavenly Father would bid us pray, and then refuse to hear, or give us what would be hurtful.
