What does the Bible say about the wedding garment?

In the parable of the wedding garment from Matthew 22:1-14, the wedding garment represents the righteousness of Christ. This garment is necessary for anyone who wishes to attend the marriage feast of the Lamb. Without it, those who try to enter dressed in their own self-righteousness will find themselves rejected. The king in the parable questions one guest without the wedding garment, and his inability to respond highlights the futility of attempting to stand before God in our own works. This underscores the necessity of being clothed in Christ’s righteousness to enter the kingdom of heaven.
