Context: 1 Corinthians 1:26-31 applies the theology of the cross (vv. 18-25) to the Corinthian congregation itself. Paul reminds them of their own calling—"not many were wise by human standards, not many were powerful, not many were of noble birth." God chose the foolish, weak, and despised to shame the wise and strong, "so that no one may boast in His presence" (v. 29). Paul then quotes Jeremiah 9:23-24: "Let him who boasts boast in the Lord" (v. 31).

OT-to-OT Development: Paul applies the entire wisdom/foolishness trajectory:

• Jeremiah 9:23-24 (quoted in v. 31): Boast only in knowing the LORD
• Isaiah 29:14 (foundation of vv. 18-25): Wisdom of wise will perish
• 1 Samuel 2:7-8 (Hannah's song echoed): "The LORD brings low and He exalts; He raises the poor from the dust"

Connections:

• TO:
• Jeremiah 9:23-24 - proper boasting
• 1 Samuel 2:1-10 - Hannah's reversal song
• Deuteronomy 7:7 - God chose Israel not because they were great
• FROM OT:
• All OT instances of God choosing the lowly and shaming the proud
• FROM NT:
• James 2:5 - "Has not God chosen the poor in the eyes of the world to be rich in faith?"
• 1 Corinthians 4:10 - "We are fools for Christ"
• 2 Corinthians 10:17 - quotes Jeremiah 9:24 again

Christological Connection: 1 Corinthians 1:26-31 shows that the cross's reversal extends beyond Christ's own crucifixion to the composition of His church. Just as God chose the "foolishness" of the cross to accomplish redemption, so He chooses the foolish, weak, and despised to be His people—"so that no one may boast in His presence" (v. 29). This fulfills Jeremiah 9:23-24's command: boasting must be in the LORD alone, not in human wisdom, strength, or status. Christ Himself has become "our wisdom from God: our righteousness, holiness, and redemption" (v. 30). Everything believers have—including wisdom, standing before God, and salvation—is pure gift in Christ. The proper response is the one Jeremiah prescribed: "Let him who boasts boast in the Lord" (v. 31).

Connection Method(s): Promise-Fulfillment, Analogy — The cross's wisdom-overturning pattern extends analogically to the church's composition as God chooses the foolish and weak, fulfilling Jeremiah 9:23-24's command that boasting be in the LORD alone, with Christ as believers' wisdom, righteousness, and redemption.
