How do we know that Jesus is our advocate according to the Bible?

In 1 John 2:1, it is clearly stated that Jesus Christ is our advocate with the Father. This means that Jesus intercedes for us, presenting His righteousness in defense of those who believe in Him. Unlike a traditional lawyer who argues for the innocence of a client, Jesus pleads His own righteousness before God, affirming that the penalty for our sins has already been paid by His sacrificial death. His advocacy is rooted in His perfect obedience to the law and the atonement He provided, which assures believers that God is just in forgiving our sins. This understanding of Jesus as our advocate is crucial for Christians as it not only provides reassurance of forgiveness but also highlights the relational aspect of our connection to God through Christ.
