Why is understanding our need for God's grace important for Christians?

The experience of Joshua the high priest in Zechariah 3 serves as a powerful reminder of humanity's inherent sinfulness and the necessity for God's grace. Joshua's filthy garments represent the sin that separates us from God. When God removes those garments and replaces them with new clothing, it signifies the cleansing and righteousness that come solely from Him. This understanding fosters humility and gratitude in believers, urging them to rely on Christ's finished work rather than their own efforts. Recognizing our endless need for grace is foundational for growth in faith and assurance in God's promises.
