What does the parable of the great supper teach about who is called to Christ?

The parable of the great supper in Luke 14 highlights the invitation to the feast, symbolizing the gospel call to salvation. The ones initially invited - the self-righteous and affluent - make excuses, illustrating the indifference of those who trust in their works. Contrary to the expectations of society, it is the poor, the maimed, and the blind who respond to Christ's call, demonstrating that God’s grace is extended to the undeserving. This teaches that the true captives of grace are those who acknowledge their need, rather than those who are confident in their own righteousness.
