1 Corinthians 1:30,31 - Joseph Benson’s Commentary on the Old and New Testaments

But of him Of his free mercy and grace; are ye in Christ Jesus Ingrafted into him, and therefore possessed of an interest in him, and union with him; who of God The original source of our salvation in all its parts, and of all the gifts and graces we possess; is made unto us who now believe But were formerly ignorant and foolish; wisdom Teaching us by his word and Spirit, and making us wise unto salvation; righteousness The procuring cause of justification through his obedience unto death, to us who were before under guilt, condemnation, and wrath; sanctification The principle and example, source and author of universal holiness to us, whereas before we were altogether polluted and dead in sin; and redemption Complete deliverance from all the consequences of sin, and especially from death, the punishment of it, by a glorious resurrection, (termed the redemption of our body, Romans 8:23,) and eternal bliss both of soul and body. That, as it is written, (see on Jeremiah 9:23-24,) He that glorieth, let him glory in the Lord Not in himself, not in the flesh, not in the world, not in any creature, nor in any endowment or qualification, mental or bodily.
