(Isa 45:1-4) The deliverance of the Jews by Cyrus.
(Isa 45:5-10) God calls for obedience to his almighty power.
(Isa 45:11-19) The settlement of his people.
(Isa 45:20-25) The conversion of the Gentiles.
Cyrus is called God's anointed; he was designed and qualified for his great service by the counsel of God. The gates of Babylon which led to the river, were left open the night that Cyrus marched his army into the empty channel. The Lord went before him, giving entrance to the cities he besieged. He gave him also treasures, which had been hidden in secret places. The true God was to Cyrus an unknown God; yet God foreknew him; he called him by his name. The exact fulfilment of this must have shown Cyrus that Jehovah was the only true God, and that it was for the sake of Israel that he was prospered. In all the changes of states and kingdoms, God works out the good of his church.
There is no God beside Jehovah. There is nothing done without him. He makes peace, put here for all good; and creates evil, not the evil of sin, but the evil of punishment. He is the Author of all that is true, holy, good, or happy; and evil, error, and misery, came into the world by his permission, through the wilful apostacy of his creatures, but are restrained and overruled to his righteous purpose. This doctrine is applied, for the comfort of those that earnestly longed, yet quietly waited, for the redemption of Israel. The redemption of sinners by the Son of God, and the pouring out the Spirit, to give success to the gospel, are chiefly here intended. We must not expect salvation without righteousness; together the Lord hath created them. Let not oppressors oppose God's designs for his people. Let not the poor oppressed murmur, as if God dealt unkindly with them. Men are but earthen pots; they are broken potsherds, and are very much made so by mutual contentions. To contend with Him is as senseless as for clay to find fault with the potter. Let us turn God's promises into prayers, beseeching him that salvation may abound among us, and let us rest assured that the Judge of all the earth will do right.
Believers may ask in prayer for what they need; if for their good, it will not be withheld. But how common to hear God called to account for his dealings with man! Cyrus provided for the returning Jews. Those redeemed by Christ shall be provided for. The restoration would convince many, and convert some; and all that truly join the Lord, find his service perfect freedom. Though God be his people's God and Saviour, yet sometimes he lays them under his frowns; but let them wait upon the Lord who hides his face. There is a world without end; and it will be well or ill with us, according as it shall be with us in that world. The Lord we serve and trust, is God alone. All that God has said is plain, satisfactory, and just. As God in his word calls us to seek him, so he never denied believing prayers, nor disappointed believing expectations. He gives grace sufficient, and comfort and satisfaction of soul.
The nations are exhorted to draw near to Jehovah. None besides is able to help; he is the Saviour, who can save without the assistance of any, but without whom none can save. If the heart is brought into the obedience of Christ, the knee will cheerfully obey his commands. To Christ men shall come from every nation for blessings; all that hate his cause shall be put to shame, and all believers shall rejoice in him as their Friend and Portion. All must come to him: may we now come to him as the Lord our Righteousness, walking according to his commandments.
