The sin that most grieves God's heart is unbelief. In this classic sermon, David Wilkerson preached about how the book of Hebrews points to the vital importance of faith. God uses the story about unbelief among the Israel nation in the desert wanderings to illustrate how our lack of faith breaks his heart. Modern believers are no better than the Israelites of those ancient days, so we should see the Exodus story as a warning against not taking faith seriously. Our heavenly Father desires our trust in him and his goodness.

Many believers struggle to understand what exactly the Holy Spirit empowers us to do in the world. Is it to build earthly kingdoms for God? Is it to overcome evil worldly governments with God's power? In this sermon, David Wilkerson speaks about the heavenly kingdom that God has given us the Spirit to build instead. His Spirit lives in us to glorify the Father through our lives.
