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; 2 and He Himself is the propitiation for our sins; and not for ours only, but also for those of the whole world.
1 John 2:1-2 (NASB)
An advocate is someone who is on your side, pleading your case. Think of the woman caught in adultery. She was actually guilty. So He isn’t just pleading your cause when you are in the right. He is especially pleading your cause when you are wrong, when you have sinned. He is your advocate when you most need one and when you least deserve one.
In the book of Job, it is Satan who is before the Father accusing us. The Father is only seeking justice; but that is a problem if you are the sinner! Without Jesus, the guilt is going to stick to you. In Jesus, we can say that we love the person but hate the sin, because that is what the Father does when He listens to the Son as our advocate.
The Father is going to listen to Jesus! Jesus is saying, “Yes, all those accusations are true, and I died for them. Are you going to say that my death was to no account, Dad?” And the Father will say, “Of course not!”
