Carter Conlon emphasizes that we are living in a foolish time that demands a response from Christians. He highlights the increasing immorality and mockery of morality in society, urging believers to stand firm in their faith and speak out against the foolishness around them. Conlon draws from Proverbs to illustrate the need for discernment in how to respond to folly, advocating for a spirit-led approach that reflects Christ's love and truth. He calls for a return to prayer and reliance on the Holy Spirit to empower believers to make a difference in a world that desperately needs the light of Christ. Ultimately, he challenges the church to rise up and be a bold witness in these challenging times.
