1 John 2:1-2
“My little children, I am writing these things to you so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous"
Here the Apostle John is telling us that Jesus is our "Advocate", (Attorney, Proxy and Friend) who presents the key evidence for our defense against sin, which is His blood.
Because Christ, is the only blameless example of human nature, He alone can intercede on our behalf with God. He is the propitiation (v.2) for our sins; and those of the entire world. All men, in every land, and through successive generations, are invited to come to God through this all-sufficient atonement, and by this new and living way.
The Truth
“Christ suffered for our sins once for all time. He never sinned, but he died for sinners to bring you safely home to God. He suffered physical death, but he was raised to life in the Spirit.” (1 Peter 3:18)
