In this message from Luke 15:4–7, we see the heart of the Good Shepherd who leaves the ninety-nine to seek the one lost sheep. Jesus reminds us that every soul matters and that heaven rejoices when one sinner repents. This sermon challenges every believer to identify one person God has placed in their life, pray faithfully for them, lovingly share the gospel, and intentionally pursue them with the hope of Christ. The same Savior who came searching for us now sends us to reach our one.
