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.
Jesus said, "This is the commandment that I give unto you, that ye love one another" ( John 13:34-35 ). I can say, "Oh yes, I have His commandments, He told me to love one another," and yet, you hate everybody. You see, having the commandment isn't enough. How can I know that I know Him? If I keep His commandment!
