Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace, with which he has blessed us in the Beloved. In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known to us the mystery of his will, according to his purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.

In him we have obtained an inheritance, having been predestined according to the purpose of him who works all things according to the counsel of his will, so that we who were the first to hope in Christ might be to the praise of his glory. In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory. (ESV)

God has chosen the foolish things of the world to shame the wise, and God has chosen the weak things of the world to shame the things which are strong, and the base things of the world and the despised God has chosen, the things that are not, so that He may nullify the things that are, so that no man may boast before God. But by His doing you are in Christ Jesus, who became to us wisdom from God, and righteousness and sanctification, and redemption, so that, just as it is written, “LET HIM WHO BOASTS, BOAST IN THE LORD.”(NASB)

Let us be exhorted to exalt God alone, and ascribe to him all the glory of redemption. Let us endeavor to obtain, and increase in, a sensibleness of our great dependence on God, to have our eye to him alone, to mortify a self-dependent and self-righteous disposition. Man is naturally exceeding prone to exalt himself, and depend on his own power or goodness; as though from himself he must expect happiness. He is prone to have respect to enjoyments alien from God and his Spirit, as those in which happiness is to be found.—But this doctrine should teach us to exalt God alone: as by trust and reliance, so by praise. Let him that glorieth, glory in the Lord. Hath any man hope that he is converted, and sanctified, and that his mind is endowed with true excellency and spiritual beauty? That his sins are forgiven, and he received into God’s favor, and exalted to the honor and blessedness of being his child, and an heir of eternal life? Let him give God all the glory; who alone makes him to differ from the worst of men in this world, or the most miserable of the damned in hell. Hath any man much comfort and strong hope of eternal life, let not his hope lift him up, but dispose him the more to abase himself, to reflect on his own exceeding unworthiness of such a favor, and to exalt God alone. Is any man eminent in holiness, and abundant in good works, let him take nothing of the glory of it to himself, but ascribe it to him whose “workmanship we are, created in Christ Jesus unto good works.”
