The sermon message in the SERVE series concludes with a focus on the Great Commission from Matthew 28:18-20. Jesus commissions his disciples to go and make disciples of all nations, baptizing them and teaching them to obey his commands. This mission is emphasized as not just a task but a co-mission for every believer.

The sermon stresses that the church exists not for comfort or personal gain, but to reach out to the lost and hurting. It challenges believers to move beyond mere attendance and involvement in church activities to actively engaging with others, just as Jesus did with notorious sinners and outcasts. The message highlights that involvement in God's mission may be messy and uncomfortable at times, but it's essential for fulfilling God's purpose.

Key points include:
- Emphasizing the Great Commission as the purpose of the church.
- Encouraging believers to go beyond comfort zones to reach the lost.
- Illustrating Jesus' example of involvement with people in need.
- Affirming that the church's growth and impact depend on active involvement in God's mission.

Ultimately, the sermon calls for a deep involvement in sharing God's love and truth with others, echoing Jesus' radical approach of reaching out to those in need and affirming that everyone, regardless of their background or struggles, belongs in God's family.
