Pastor Jamie Self powerfully contrasts worldly boasting with godly confidence, drawing from Jeremiah 9 and the story of David and Goliath to show that true life begins by boasting in the Lord alone. He explains that Israel’s downfall came from trusting in their own wisdom, strength, and riches rather than acknowledging and fearing God, which ultimately led to divine judgment and death. The sermon concludes by emphasizing that in Christ, believers receive wisdom, righteousness, and redemption—making Him the only worthy object of our boasting and the true source of life.
