True preaching always involves explicatio et applicatio verbi Dei (the explication and application of the Word of God).

John Carrick, The Imperative of Preaching, 29.

In each of the individual, historical covenantal administrations, the intended end of God’s covenantal work is stated in terms of “the Immanuel principle”—“I shall be your God and you shall be My people.” With these words, God promises to be Immanuel (which means “God with us”) to His people. God first articulates this principle to Abraham in Genesis 17:7. He has Moses reiterate it to the Israelites prior to the exodus in Exodus 6:7. The Immanuel principle then is connected with the Davidic covenant in 2 Samuel 7:14 and, after the exile, gives shape to the new covenant that the prophets proclaim to Israel in Ezekiel 36:28 and Jeremiah 31:33. Finally, 2 Corinthians 6:16 uses it to articulate what God is doing in the New Testament church, even as Revelation 21:3 proclaims it as the glorious bliss of the new heavens and the new earth. Running throughout all of the biblical covenants, there is this striking unity of purpose. God will have His people.

In Romans 16:20, Paul uses the specific imagery of Genesis 3:15 to describe what God is doing, right that moment, in and through His church. In 1 John 3:8, John speaks of Jesus as coming specifically to destroy the works of the devil. In Hebrews 2:14, the Scriptures speak of Jesus Christ as the destroyer of the devil himself. In Revelation 12, John uses the imagery of Genesis 3:15 to encapsulate and represent the entire progress of redemptive history. Repeatedly, the Scriptures evoke Genesis 3:15 to crystallize what God has been doing, and what He presently is doing, in His redemptive work.

As for us, we prefer to listen to Augustine, when he says: “To declare publicly what you have received is not arrogance, but faith; it isn’t haughtiness, but devotion.” (On the Words of the Lord according to Luke, Sermon 28).

But the object of perseverance are the promises of divine grace. The certainty of these promises rests not only in the one who makes the promises, and in the promises themselves, but they are also certain to the persevering person.

It is clear enough from what Paul states in Rom 8:30 that reprobates are never justified. . . . And although there are some among the reprobates who are reported somehow to belong to Christ because they confessed their faith, shared in the sacraments, and used the name of the Church and associated with it — they were not, in actual fact, in Christ. They appeared to be within the boundaries of faith, but they were believers in appearance only, “adhering only to professing Christ, but not binding themselves with cords of love” (Cyril, On John, book 10, chapter 24).

And that saving faith is a firm assent — based on the certain knowledge of divine revelation — ingenerated in our minds by the Holy Spirit through the word of the Gospel, an assent to everything that God has revealed to us in his Word, and especially the promises of life that were made in Christ; hereby each and every believer, relying with constant confidence in God, steadfastly determines that forgiveness of sins was promised not only to believers generally but also granted to him in particular, and that he himself has received eternal righteousness and from it, life, out of God’s mercy because of the merit of Jesus Christ alone.

Along with Scripture itself we willingly grant that when one hears the Word of God it is “the power of God for those who are being saved” (1 Cor 1:18), that it “is the seed that has been sown in our hearts” (Luke 8:11), and that it “is a two-edged sword piercing the soul” (Heb 4:12). Nevertheless, we disagree with those who ascribe a power of the following sort to the outward preaching of the Gospel as it strikes the ears: that ingenerating faith is a property inherent in the preaching, as though the very performance of that action achieves it, and as though the operation of the Holy Spirit is bound up in it. Even though by God’s command the outward preaching is a necessary prerequisite of faith for adults, nevertheless the outward act of preaching is not sufficient for faith if it is not accompanied by the efficacy of the Holy Spirit as he reveals the meaning of the Gospel inwardly and as he presents and seals it upon the ‘ears’ of the heart. For “neither he who plants is anything, nor is he who waters, but he who grants the increase — God” (1 Cor 3:7). We must therefore see to it here that we not go head over heels to the extremes and pull apart what belongs together, or mix up what should be kept apart, but attributing to the instrument what belongs properly to the primary cause, and with the same sense. Nor should we do so by looking for the Spirit apart from the Word, or by looking for an understanding of the Word apart from the internal revelation of the Spirit; or, once the Word is understood, by looking for the assent and true confidence form the Word itself (or from the one who administers it) apart from the internal revelation by the Spirit, and to do so by the light of our understanding.

Because of the variety in the concurrence of the internal call with the outward one, hypocrites mingle among the true people of Israel within the visible Church (which is the gathering of those who have been called). It is with regard to this mixture that both the good and the evil are said to be invited to the wedding banquet of the Son, the Lamb of God (Matt 22:4), and that many are called, but few are chosen (Matt 20:16).

The way of calling, when we examine it from opposing perspectives, is divided into external and internal. The former is achieved outwardly through the administration of the Word and sacraments, the latter inwardly through the working of the Holy Spirit.
