This document provides a summary and analysis of 1 John 2:1-2. It discusses how Jesus was the greatest sacrifice by being the atoning sacrifice for our sins and for the sins of the whole world. It explains that Jesus is our advocate with the Father and the propitiation for our sins, meaning he appeases God's wrath and turns it away from us. Having Jesus as our advocate and propitiation encourages us to not sin and recognizes our liability to sin despite being good people, while also providing gracious forgiveness for when we do sin.
