The third petition is, THY WILL BE DONE ON EARTH AS IT IS IN HEAVEN. Though this depends on his kingdom, and cannot be disjoined from it, yet a separate place is not improperly given to it on account of our ignorance, which does not at once or easily apprehend what is meant by God reigning in the world. This, therefore, may not improperly be taken as the explanation, that God will be King in the world when all shall subject themselves to his will. We are not here treating of that secret will by which he governs all things, and destines them to their end (see chap. xxiv. s.17). For although devils and men rise in tumult against him, he is able by his incomprehensible counsel not only to turn aside their violence, but make it subservient to the execution of his decrees. What we here speak of is another will of God, namely, that of which voluntary obedience is the counterpart; and, therefore, heaven is expressly contrasted with earth, because, as is said in The Psalms, the angels "do his commandments, hearkening unto the voice of his word" (Ps.103:20). We are, therefore, enjoined to pray that as everything done in heaven is at the command of God, and the angels are calmly disposed to do all that is right, so the earth may be brought under his authority, all rebellion and depravity having been extinguished. In presenting this request we renounce the desires of the flesh, because he who does not entirely resign his affections to God, does as much as in him lies to oppose the divine will, since everything which proceeds from us is vicious. Again, by this prayer we are taught to deny ourselves, that God may rule us according to his pleasure; and not only so, but also having annihilated our own may create new thoughts and new minds so that we shall have no desire save that of entire agreement with his will; in short, wish nothing of ourselves, but have our hearts governed by his Spirit, under whose inward teaching we may learn to love those things which please and hate those things which displease him. Hence also we must desire that he would nullify and suppress all affections which are repugnant to his will.
Such are the three first heads of the prayer, in presenting which we should have the glory of God only in view, taking no account of ourselves, and paying no respect to our own advantage, which, though it is thereby greatly promoted, is not here to be the subject of request. And though all the events prayed for must happen in their own time, without being either thought of, wished, or asked by us, it is still our duty to wish and ask for them. And it is of no slight importance to do so, that we may testify and profess that we are the servants and children of God, desirous by every means in our power to promote the honour due to him as our Lord and Father, and truly and thoroughly devoted to his service. Hence if men, in praying that the name of God may be hallowed, that his kingdom may come, and his will be done, are not influenced by this zeal for the promotion of his glory, they are not to be accounted among the servants and children of God; and as all these things will take place against their will, so they will turn out to their confusion and destruction.
