This sermon centers on the parable of the great supper in Luke 14, using it as a powerful metaphor for God's gracious invitation to salvation and ongoing opportunities for service. It emphasizes that while many reject God's invitation due to worldly distractions—such as material pursuits, family obligations, or personal security—the heart of God is grieved by such rejection, yet He remains eager to fill His house with the marginalized and the overlooked. The message expands beyond initial conversion to highlight that every believer is continually invited to participate in God's mission through daily acts of surrender, where even small, intentional steps—like sharing faith work, feeding the hungry, listening to the hurting, or serving in local outreach—become divine appointments. The preacher underscores that true discipleship is not measured by grand gestures but by availability, obedience, and a willingness to say 'here am I, send me,' recognizing that God honors not just what we give, but who we become when we make ourselves ready to serve. Ultimately, the call is to be more open, present, and willing to walk through the doors of opportunity that God places before us.
