Isaiah 59:21
"As for Me, this is My covenant with them," says the LORD. "My Spirit will not depart from you, and My words that I have put in your mouth will not depart from your mouth or from the mouths of your children and grandchildren, from now on and forevermore," says the LORD.
“As for Me, this is My covenant with them,” says the LORD.

The Lord pledges Himself to the redeemed people of Zion, whom He has delivered from transgression through the coming Redeemer (Isaiah 59:20). His covenant rests upon His faithfulness and continues His saving purpose revealed through Abraham, Israel, and David. Israel’s repeated failures do not nullify God’s purpose; He remains committed to preserving a people for His name and fulfilling His promises.

Isa 61:8 For I, the LORD, love justice; I hate robbery…
Jer 32:40 I will make an everlasting covenant with them…

“My Spirit will not depart from you,

God promises an abiding presence rather than the temporary empowerments often seen under the old covenant. The Holy Spirit would sustain His people in faith, obedience, worship, and witness. The promise anticipates the new covenant, in which God gives His Spirit to dwell with His people permanently through the work of Christ.

Ezk 36:27 And I will put My Spirit within you and cause you…
Jhn 14:16-17 And I will ask the Father, and He will give you another…

and My words that I have put in your mouth will not depart from your mouth

God’s revealed word is to remain the confession and proclamation of His redeemed people. As the Lord placed His words in the mouths of His prophets, He ensures that His truth will continue to be declared among those who belong to Him. His word does not perish with one generation or depend upon human strength for its preservation.

Jer 1:9 Then the LORD reached out His hand, touched my mouth……
Deu 30:14 But the word is very near you; it is in your mouth…

or from the mouths of your children and grandchildren,

God’s covenant mercy extends through succeeding generations. Parents and elders bear the responsibility of teaching God’s works, commands, and promises to their children, so that each generation may know the Lord and speak His truth. The promise also assures that God will preserve a faithful witness among His people.

Deu 4:9 Only be on your guard and diligently watch yourselves…
Jol 1:3 Tell it to your children; let your children…

from now on and forevermore,”

The Lord’s commitment reaches beyond the immediate restoration of Israel and points to His everlasting kingdom. What God establishes by His Spirit and word endures because He is unchanging and His purposes cannot fail.

Psa 115:18 But it is we who will bless the LORD, both now…
Psa 121:8 The LORD will watch over your coming and going…

says the LORD.

The certainty of the covenant rests on the authority of the Lord Himself. His declaration guarantees the future of His people, the abiding work of His Spirit, and the continuing testimony of His word.

Mal 1:2 “I have loved you,” says the LORD. But you ask……
Isa 44:6 Thus says the LORD, the King and Redeemer of Israel…

Flimsy Garments
'Their webs shall not become garments.'--ISAIAH lix. 6. 'I counsel thee to buy of me ... white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear.'--REV. iii. 18. The force of these words of the prophet is very obvious. He has been pouring out swift, indignant denunciation on the evil-doers in Israel; and, says he, 'they hatch cockatrice's eggs and spin spiders' webs,' pointing, as I suppose, to the patient perseverance, worthy of a better cause, which bad men

Salvation
ISAIAH lix. 15, 16. And the Lord saw it, and it displeased him that there was no judgment. And he saw that there was no man, and wondered that there was no intercessor: therefore his arm brought salvation unto him, and his righteousness it sustained him. This text is often held to be a prophecy of the coming of our Lord Jesus Christ. I certainly believe that it is a prophecy of his coming, and of something better still; namely, his continual presence; and a very noble and deep one, and one from

How Shall one Make Use of Christ as the Life, when Wrestling with an Angry God Because of Sin?
That we may give some satisfaction to this question, we shall, 1. Shew what are the ingredients in this case, or what useth to concur in this distemper. 2. Shew some reasons why the Lord is pleased to dispense thus with his people. 3. Shew how Christ is life to the soul in this case. 4. Shew the believer's duty for a recovery; and, 5. Add a word or two of caution. As to the first, There may be those parts of, or ingredients in this distemper: 1. God presenting their sins unto their view, so as

'The Breastplate of Righteousness'
'Having put on the breastplate of righteousness.'--Eph. vi. 14. There can be no doubt that in this whole context the Apostle has in mind the great passage in Isaiah lix. where the prophet, in a figure of extreme boldness, describes the Lord as arming Himself to deliver the oppressed faithful, and coming as a Redeemer to Zion. In that passage the Lord puts on righteousness as a breastplate--that is to say, God, in His manifestation of Himself for the deliverance of His people, comes forth as if arrayed

"For the Law of the Spirit of Life in Christ Jesus Hath Made Me Free from the Law of Sin and Death. "
Rom. viii. 2.--"For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death." That which makes the delivery of men from the tyranny of sin and death most difficult, and utterly impossible unto nature, is, that sinners have given up themselves unto it, as if it were true liberty, that the will and affections of men are conquered, and sin hath its imperial throne seated there. Other conquerors invade men against their will, and so they rule against their will.

The Hindrances to Mourning
What shall we do to get our heart into this mourning frame? Do two things. Take heed of those things which will stop these channels of mourning; put yourselves upon the use of all means that will help forward holy mourning. Take heed of those things which will stop the current of tears. There are nine hindrances of mourning. 1 The love of sin. The love of sin is like a stone in the pipe which hinders the current of water. The love of sin makes sin taste sweet and this sweetness in sin bewitches the

Wherefore Christ Undertook a Method of Setting us Free So Painful and Laborious, when a Word from Him, or an Act of his Will, Would Alone
Wherefore Christ undertook a method of setting us free so painful and laborious, when a word from Him, or an act of His will, would alone have sufficed. 19. Then he labours to teach and persuade us that the devil could not and ought not to have claimed for himself any right over man, except by the permission of God, and that, without doing any injustice to the devil, God could have called back His deserter, if He wished to show him mercy, and have rescued him by a word only, as though any one denies

"And we all do Fade as a Leaf, and Our Iniquities, Like the Wind, have Taken us Away. "
Isaiah lxiv. 6.--"And we all do fade as a leaf, and our iniquities, like the wind, have taken us away." Here they join the punishment with the deserving cause, their uncleanness and their iniquities, and so take it upon them, and subscribe to the righteousness of God's dealing. We would say this much in general--First, Nobody needeth to quarrel God for his dealing. He will always be justified when he is judged.

Covenanting Provided for in the Everlasting Covenant.
The duty of Covenanting is founded on the law of nature; but it also stands among the arrangements of Divine mercy made from everlasting. The promulgation of the law, enjoining it on man in innocence as a duty, was due to God's necessary dominion over the creatures of his power. The revelation of it as a service obligatory on men in a state of sin, arose from his unmerited grace. In the one display, we contemplate the authority of the righteous moral Governor of the universe; in the other, we see

An Analysis of Augustin's Writings against the Donatists.
The object of this chapter is to present a rudimentary outline and summary of all that Augustin penned or spoke against those traditional North African Christians whom he was pleased to regard as schismatics. It will be arranged, so far as may be, in chronological order, following the dates suggested by the Benedictine edition. The necessary brevity precludes anything but a very meagre treatment of so considerable a theme. The writer takes no responsibility for the ecclesiological tenets of the
