It is the language of infinite mercy, speaking to the abject condition of mankind. We have become naked, and poor, and miserable through sin, and God, instead of driving us from his presence, comes loaded with mercy, And thus he speaks to us.
Isaiah 55:1. 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.
See the freeness of divine love! See how God who knows the wants of souls, provides all things needful for them water the water of life; and as if that were not enough, the wine of joy, the milk of satisfaction; and he offers these freely. But, mark, there is no gain for him: the gain is for ourselves, for he saith, «He that hath no money, buy wine and milk without money and without price.» All that you want, dear friend, God is ready to give you. Do you want these good things? Then come and welcome. It is God who bids you come.
Isaiah 55:2. Wherefore do ye spend money for that which is not bread? and your labour for that which satisfieth not?
Why do you seek to get comfort for your souls where you will never get it? Why do you try to content your immortal nature upon things that will die? There is nothing here below that can satisfy you. Why spend your money then for these things, and your labour for nothing?
Isaiah 55:2. Hearken diligently unto me, and eat ye that which is good, and let your soul delight itself in fatness.
God has real food for your soul something that will make you truly happy. He will satisfy you, not with the name of goodness, but with the reality of it, if you will but come and have it. You shall have fullness you shall have delight if you are but willing to come and receive it.
Isaiah 55:3. Incline your ear, and come unto me: hear, and your soul shall live;
Then who would not hear who would not give the attention if by that attention life immortal may be received?
Isaiah 55:3. And I will make an everlasting covenant with you, even the sure mercies of David.
Will God enter into covenant with sinful men with thirsty men with hungry men with needy men with guilty men? Ah! that he will. «I will make an everlasting covenant with you, even the sure mercies of David.»
Isaiah 55:4. Behold, I have given him
That is the Son of David Jesus the Christ «I have given him.»
Isaiah 55:4. For a witness to the people, a leader and commander to the people.
If you want anyone to tell you what God is, Jesus Christ is the witness to the character of God. Do you want a leader to lead you back to peace and happiness a commander by whose power you may be able to fight Satan and all the powers of darkness that hold you in bondage? Has all in Jesus Christ that I can need for time and eternity, and this can all be mine for the asking, and receiving. Shall we not ask and receive?
