David Wilkerson emphasizes that true joy comes from understanding the 'joyful sound' described in Psalms 89:15, which signifies a revelation that leads to a fulfilled and victorious life. This joyful sound, rooted in the concept of Jubilee, represents liberation and God's promises, allowing believers to walk in peace and strength. Wilkerson explains that those who grasp this sound become fearless and self-assured, empowered by the Holy Spirit to overcome life's challenges. He connects this joyful sound to Jesus Christ, who embodies the essence of Jubilee, offering freedom and restoration to all. Ultimately, the message is one of hope and the invitation to live joyfully in the light of God's presence.

The psalmist writes of a glorious secret to enjoying a fulfilled, joyful life: “Blessed are the people who know the joyful sound! They walk, O Lord, in the light of Your countenance” (Psalm 89:15). The Hebrew meaning of this verse suggests, “Those who have a revelation of the joyful sound will wake up every day with peace, strength and happiness. Their life will be filled with the joy of the morning sun.” In short, the psalmist is telling us, “There is a certain, joyful sound that is of such powerful significance that it is the very foundation of victorious living. If you know and understand this sound, you will be changed from glory to glory.” “All who know the meaning of the joyful sound become self-assured, fearless. They walk through life with an every-increasing sense of security. They are able to overcome, even when being sifted by Satan. Their hearts are steadfast and at rest — because the Holy Spirit has revealed to them the meaning behind the joyful sound!” So what is this joyful sound? It is the sound of Jubilee! It would take too long to explain the history of the Jewish Festival of Jubilee but it is found in Leviticus 25 and is an exciting, liberating study about God’s promises, provision and blessing. The prophet Isaiah declares that Jesus Christ is our Jubilee. He writes, “[The Lord] has sent Me to … proclaim liberty to the captives, and the opening of the prison to those who are bound; to proclaim the acceptable year of the Lord” (Isaiah 61:1-2). Isaiah is using the language of Jubilee here: “Let the trumpets blast, announcing the joyous year of liberty our Savior has given us.” This was the joyful sound — proclaiming to all mankind: “I have made provision for you — to walk out of prison, be restored to your family and have everything you need for a fulfilled life. You are free to live without fear of any enemy. Enter now into my joy!”
