The sermon explored the nature of a confusing commission, drawing from Luke 24 and Acts 10 to illustrate God's call to witness, even amidst uncertainty and personal discomfort. It emphasized that true obedience involves surrendering to the Holy Spirit's leading, recognizing that God's plan often unfolds in unexpected ways, and that the harvest of souls awaits those willing to step out in faith, whether through traditional missionary work or everyday encounters, ultimately affirming that the church's purpose is to share the gospel and witness to the transformative power of Jesus Christ.
