What does it mean to be robed in the righteousness of Christ?

To be robed in the righteousness of Christ signifies that believers are covered by His perfect obedience and sacrifice, making them acceptable before God. This is illustrated in the parable of the wedding feast in Matthew 22, where the king provides garments for his guests. The absence of the proper robe resulted in judgment, illustrating that without Christ's righteousness, one cannot stand before God. As Paul states in Philippians 3:8-9, being found in Christ means not having a righteousness of my own but that which is through faith in Him. Thus, our standing before God is entirely based on Christ's atoning work and the imputed righteousness He freely gives to those who believe.
