Matthew 22:43

He saith unto them, How then doth David in spirit call him Lord, saying,

The words in spirit mean that David spoke by the Spirit of inspiration from God when he called the Messiah his Lord. With that question Jesus was testing his hearers, the Pharisees, to see whether they recognized the Messiah as more than David's merely human descendant. They could readily answer that the Messiah was David's son, yet they could not explain how David could then also call him Lord.

The answer is that the Messiah is both: David's direct descendant according to the flesh, and at the same time David's divine Lord. The Son of David is also the Son of God, divine in character and possessing divine authority. David foresaw Christ entering heaven and taking His place at God's right hand. The outpouring of the Holy Spirit at Pentecost testified that the crucified Jesus had received that authority in heaven and on earth as priest and king, the Anointed One over His people.

The same question is raised in connection with the wedding parable, particularly the man without a wedding garment, to challenge the view that the church is the Lamb's bride and that the marriage occurs after Christ returns. It belongs to Jesus' warning that rejecting the Son of God brings judgment. What was addressed to the Jews applies in every age, so those who refuse Christ as Redeemer will face the doom foreshadowed by His examples unless they repent.
