In his sermon, Marty emphasizes the importance of building lives, marriages, families, and a community of disciples who surrender to Christ, aiming for a legacy that lasts into eternity. Drawing from the story of Nehemiah, Marty illustrates how God uses unlikely people to accomplish His work, highlighting four key necessities for being on mission with God: watchful patience, strong courage, deep reliance on God, and intentional readiness. Marty challenges you to recognize God's ongoing work around you and to join His mission, just as Jesus did, by surrendering your life fully to God's purpose.
