Leonard Ravenhill emphasizes the profound love of Jesus Christ for sinners, illustrating this through the parables of the lost sheep, the lost coin, and the prodigal son. He highlights that while many things Jesus said and did are not recorded in the Bible, the essence of His mission to seek and save the lost is clear. Ravenhill passionately calls for the church to actively pursue the lost, reminding believers that every individual matters to God and that there is great rejoicing in heaven over one sinner who repents. He challenges the church to reflect on its own failures in reaching out to the lost and to embrace the urgency of sharing the Gospel. Ultimately, he underscores the need for personal repentance and the importance of being a compassionate and proactive witness for Christ.
