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.

 2:12-14 I am writing to you, little children, Because your sins are forgiven you through his name. I am writing to you, fathers, Because you have come to know him who is from the beginning. I am writing to you, young men, Because you have overcome the Evil One. I have written to you, little ones, Because you have come to know the Father. I have written to you, fathers, Because you have come to know him who is from the beginning. I have written to you, young men, Because you are strong, And the word of God abides in you, And you have overcome the Evil One.
