The first whereof is God's hearty invitation, holden forth, Isa. lv. 1, 2, 3, 4, 5.
Ho, every one that thirsteth, come ye to the waters, and he that hath no money: come ye, buy and eat; yea, come, buy wine and milk without money, and without price. Ver. 2. Wherefore do ye spend money for that which is not bread? and your labour for that which satisfieth not? Hearken diligently unto me, and eat ye that which is good, and let your soul delight itself in fatness. Ver. 3. Inclince your ear, and come unto me: hear, and your soul shall live; and I will make an everlasting covenant with you, even the sure mercies of David. Ver. 4. Behold, I have given him for a witness to the people, a leader and commander to the people, etc.
Here (after setting down the precious ransom of our redemption by the sufferings of Christ, and the rich blessings purchased to us thereby, in the two former chapters) the Lord, in this chapter,
1. Maketh open offer of Christ and his grace, by proclamation of a free and gracious market of righteousness and salvation, to be had through Christ to every soul, without exception, that truly desires to be saved from sin and wrath: "Ho, every one that thirsteth," saith he.
2. He inviteth all sinners, that for any reason stand at a distance from God, to come and take from him riches of grace, running in Christ as a river, to wash away sin, and to slocken wrath: "Come ye to the waters," saith he.
3. Lest any should stand aback in the sense of his own sinfulness or unworthiness, and inability to do any good, the Lord calleth upon such persons in special, saying, "He that hath no money, come."
4. He craveth no more of his merchant, but that he be pleased with the wares offered, which are grace, and more grace; and that he heartily consent unto, and embrace this offer of grace, that so he may close a bargain, and a formal covenant with God; "Come, buy without money, (saith he,) come, eat:" that is, consent to have, and take unto you all saving graces; make the wares your own, possess them, and make use of all blessings in Christ; whatsoever maketh for your spiritual life and comfort, use and enjoy it freely, without paying any thing for it: "Come, buy wine and milk without money, and without price," saith he.
5. Because the Lord knoweth how much we are inclined to seek righteousness and life by our own performances and satisfaction, to have righteousness and life as it were by the way of works, and how loath we are to embrace Christ Jesus, and to take life by way of free grace through Jesus Christ, upon the terms whereupon it is offered to us; therefore the Lord lovingly calls us off this our crooked and unhappy way with a gentle and timeous admonition, giving us to understand, that we shall but lose our labour in this our way: "Wherefore do ye spend your money (saith he) for that which is not bread? and your labour for that which satisfieth not?"
