Why is being clothed in Christ's righteousness important?

The idea of being clothed in Christ's righteousness is foundational to understanding salvation in sovereign grace theology. As depicted in Zechariah 3, Joshua is given a change of raiment symbolizing the removal of his filthy garments of sin and the bestowal of divine righteousness. This representation teaches us that we stand before God, justified—not because of our merits, but solely due to Christ's perfect obedience and sacrifice. Romans 4:8 states that blessed is the man to whom the Lord will not impute sin, affirming that our sins are not counted against us. This incredible truth not only provides assurance of salvation but also compels believers to live in a way that reflects the holiness of Christ, as we are called to walk in His ways as evidence of grace.
