How do we know Christ is our advocate against our sin?

The sermon emphasizes the unique role of Christ as our advocate, interceding for us to God based on His righteousness and the merits of His sacrifice. This role is crucial because it reassures believers that our sins do not disqualify us from God's grace. Hebrews 7:25 states that Jesus saves completely those who come to God through Him, indicating that His advocacy protects us against both the accusation and the condemnation of Satan. We are reminded that it is through Christ alone, and His perfect work, that we can confidently approach God in prayer and for salvation.
