Isaiah 48:6-8

GOD’S COMMUNICATIONS TO MANKIND

Isaiah 48:6. I have showed thee new things, &c.

I. The manner of God’s communications. Prophetic, addressed to the ear, and concerning things hidden from human reason. Providential, addressed to the eye. (In dealing with Isaiah 48:7, show—

1. Man’s tendency to intellectual pride.
2. How this is checked by God’s method of revelation.)
II. The manner in which they are received. With inattention; without understanding; with wilful impenitence—all arising out of natural corruption.—J. Lyth, D.D.: The Homiletical Treasury, Isaiah, p. 65.

GOD’S FOREKNOWLEDGE OF MAN’S SIN

Isaiah 48:8. Yea, thou heardest not; yea, thou knewest not, &c.

The ancient people of God were most vexatiously stolid; and although the Lord taught them very plainly and repeatedly, line upon line, &c., yet they would not understand His will. Though taught by God-sent prophets, yet the people refused to be instructed. As in a looking-class, let us see ourselves! Let the unconverted man see his own picture! God has spoken quite as pointedly to you as ever He did to the seed of Israel. He has called you by providences, &c. Three times a yea is put into our text, as if to show God’s wonder at man’s obstinacy, and the certainty that such was the state of the heart. More painful still is it to remember, that in a certain degree the same accusation may be laid at the door of believers. Even they have not such a degree of spiritual sensibility as they should have. Alas! we may well bewail ourselves that we do not hear the voice of God as we ought. Having thus reminded you of your sin, trusting we may be led to confess it with deep humility, I have now an encouraging truth to tell you, a very simple one, that all this folly, and ignorance, and obstinacy, and rebellion on our part, was foreknown by God; and notwithstanding that foreknowledge, He yet has been pleased to deal with us in a way of mercy.

I. I ADDRESS THIS TRUTH TO THE BELIEVER.

1. A mournful fact, “I knew,” &c. That word “treacherously” is one which a man would not like to have applied to himself in the common transactions of life; he would feel it to be very galling, and if there were truth in it, very degrading; and yet I question whether it will produce the same effect upon our minds when it is applied to us in relation to unfaithfulness to God. How treacherous we have been to our own vows and promises when we were first converted! This is not all. It is not merely that we have failed in promises which were made in a period of excitement, but we have been treacherous to obligations which were altogether apart from voluntary vows on our part; we have been treacherous to the most blessed relationships which mercy could have instituted. Have you not lived as if you were your own? As soldiers, by cowardice, disobedience, and desertion, we have been treacherous to a very shameful degree. Worst of all is the fact that we have been treacherous to our Lord in a relationship where fidelity constitutes the very essence of bliss, the marriage bond which exists between our soul and Christ.

2. The Divine statement of the text, that all this was known. It was no secret that we were transgressors from the womb. As the Lord foreknew the fountain of sin, so He knew all the streams which would gush from it. There are no things unknown to God. We never have surprised the Most High; we never have brought Him to such a position that He could say, “I did not know this.” We have never gone into any sin of which it could be said concerning God, that He did not know that it would so be wrought by us.

3. Seeing that this is most certain and sure, adore the amazing grace of God. You have dealt very treacherously, and yet you were redeemed not with silver and gold, &c., and you have been adopted into the Lord’s family.

4. This truth is very important to us, because in the light of it our security is clearly manifest. God can never be obstructed by a circumstance in us which can create surprise in His mind, or throw His course out of His reckoning.

5. This truth, also, should tend very much to enhance our sense of the fulness which is treasured up in Christ Jesus. The Lord our God has provided for us in Christ for all the necessities that can occur, for He has foreknown all these necessities.

II. I APPLY THIS TRUTH TO THE UNCONVERTED.

You have discovered lately the natural vileness of your heart, &c. You have a deep regret for your long delay in seeking mercy. You are willing to acknowledge that there have been special aggravations in your case. Now, the gospel of Jesus Christ is sent to you in the state in which you now are. All these sins, delays, aggravations, and rebellions of yours, were all foreknown to God; therefore, since He has sent the Gospel to you, be not slow to accept it, since it is not possible that your sins, whatever they may be, can at all militate against the fact that, if you believe and receive the Gospel, you shall be saved. Why invent a scheme by which a rebel might be saved, if He foreknew that on account of sin that rebel never could be pardoned? Do you think God would have gone farther—gone to the vast expense of providing a Saviour, if really the Gospel were null and void? He maketh not an exception. Though a man had daubed himself a thousand times with the blackest filth that ever came from hell, yet, if he believes in Jesus, God must be true to His solemn promise (H. E. I. 2332–2337).—C. H.
