Pastor William McDowell explores the biblical concept of living faithfully in challenging times, drawing primarily from the book of Habakkuk. He addresses the tension between the world's increasing darkness and the Christian's hope in God's promises. The sermon emphasizes that while believers may face trials and tribulations, they are called to live faithfully, trusting in God's character and timing rather than seeking comfort or exemption from hardship. McDowell challenges the congregation to understand their role as light in a dark world and to persevere in faith, knowing that God is faithful and that ultimate redemption is coming.
