David Wilkerson emphasizes the profound significance of the blood of Jesus Christ, which is often undervalued by many Christians. He explains that while believers may sing about its power and plead for its protection, they often lack a deep understanding of its glory and benefits. Wilkerson draws parallels between the sprinkling of blood in Exodus and the blood of Christ, highlighting that true faith in Jesus' sacrifice is essential for experiencing its protective power. He encourages believers to recognize that the blood is not just for forgiveness but also for ongoing protection and reconciliation with God. Ultimately, he calls for a deeper appreciation and acknowledgment of the precious blood of Jesus in the life of every believer.
