Passage
But of him are *ye* in Christ Jesus, who has been made to us wisdom from God, and righteousness, and holiness, and redemption;
But of him are *ye* in Christ Jesus, who has been made to us wisdom from God, and righteousness, and holiness, and redemption;
1 Corinthians 1:28 and the ignoble things of the world, and the despised, has God chosen, [and] things that are not, that he may annul the things that are;
1 Corinthians 1:29 so that no flesh should boast before God.
1 Corinthians 1:30 But of him are *ye* in Christ Jesus, who has been made to us wisdom from God, and righteousness, and holiness, and redemption;
1 Corinthians 1:31 that according as it is written, He that boasts, let him boast in [the] Lord.
The verse centers on "christ", "jesus", "been", "wisdom", "righteousness", "holiness", and "redemption". It is saying that the verse draws attention to "christ" and "jesus", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 29's "so that no flesh should boast before..." into verse 31's "that according as it is written He...", so "christ" and "jesus" belong inside that flow. In 1 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "christ" and "jesus" with trust shaped by these words, not by a vague optimism outside the passage.
