This sermon focuses on Jesus' parable of the lost sheep from Luke 15, emphasizing God's heart for seeking and saving the lost. The pastor connects this to Ezekiel 34, where God condemns shepherds who failed to care for their flocks and promises to be the true shepherd himself. The message highlights three key aspects: the shepherd's concern for every individual sheep, the shepherd's active pursuit of the lost, and the shepherd's joy in restoration. The pastor challenges the congregation to be shepherds themselves, actively seeking lost souls in their families, communities, and through various ministry opportunities. He emphasizes that every person matters to God and that Christians should share in God's mission of seeking the lost rather than being content with maintaining the status quo.
