And he is the atoning sacrifice{"atoning sacrifice" is from the Greek "hilasmos," an appeasing, propitiating, or the means of appeasement or propitiation-- the sacrifice that turns away God's wrath because of our sin.} for our sins, and not for ours only, but also for the whole world.

 2:1-2 My little children, I am writing these things to you that you may not sin. But, if anyone does sin, we have one who will plead our cause to the Father, Jesus Christ the righteous. For he is the propitiating sacrifice for our sins, and not for ours only but also for the whole world.
