In this sermon, the preacher focuses on the theme of the unheeded invitation found in the early verses of the passage. He explains that the call to the feast was rejected by those who made light of it and chose to prioritize their own interests. Despite this rejection, the grace of God is highlighted as he extends a second invitation to sinners who have defied him. The sermon also emphasizes the tragic consequences of rejecting God's invitation, drawing parallels to the historical events of the Romans' destruction of Jerusalem in 70 AD. The preacher concludes by highlighting the ongoing relevance of this message, as people continue to ignore God's invitation today.

Richard E. Bieber preaches about the significance of the River of God that flows throughout the Bible, symbolizing forgiveness and healing through water and blood. From Eden to Revelation, the River represents God's continuous presence and provision for humanity. Jesus is revealed as the ultimate source of this River, offering not just physical healing but spiritual restoration through His blood shed on the Cross. Believers are encouraged to follow the signs of healing to the source of forgiveness at Calvary, where the blood and water flowed from Jesus' side, bringing redemption and healing to all who believe.
