What does the Bible say about Christ being our advocate?

Throughout scripture, Christ is depicted as our advocate and intercessor, fulfilling this role perfectly as He stands before God on our behalf. Zechariah 3:1-4 illustrates this beautifully with Joshua the high priest, showing that the Lord rebukes Satan and removes Joshua's filthy garments, symbolizing our sins, and replaces them with righteous attire. This signifies that although we are guilty of sin, Christ, our High Priest, stands in our defense, ensuring we are not condemned but justified by His righteousness.
