Why is Christ our advocate?

In 1 John 2:1, the Apostle John reminds us that 'if any man sin, we have an advocate with the Father, Jesus Christ the righteous.' Jesus serves not only as our Savior but also as our intercessor, advocating for us before the Father. His righteousness covers our sins, allowing our attempts at holiness to be accepted, thanks to His perfect sacrifice. Furthermore, this relationship underscores the importance of recognizing our continual need for His mercy and grace, understanding that we cannot do anything acceptable in God's sight without His intervention.
