Erlo Stegen emphasizes that God is the Alpha and Omega, the beginning and the end of all things, asserting that our lives are under His sovereign control. He illustrates that regardless of human circumstances, God's purpose prevails, and we must recognize that our time on earth is appointed by Him. The sermon recounts a powerful testimony of a witch doctor who, confronted by his hidden sins, realized that nothing is concealed from the Almighty. Stegen warns that while we may enjoy our youth, we will ultimately be accountable for our actions before God. He encourages listeners to confess and forsake their sins to receive mercy, reminding them of the urgency to respond to God's call before it's too late.
