When you are in denial, the denial itself paints a picture that whatever it is you're denying is WORTH denying, because it's not good, even though WHAT you are denying is outside of your awareness. Like, as though there really is something there being denied - something you shouldn't STOP denying because then you'll be in big trouble.
It's the same with fear. Fear tells you there's something real to be afraid of, that the fear is justified. The fear says its worth being afraid, because if you aren't, you'll have to confront what it is you area afraid of. Think about that - if you're NOT afraid, you will have to FACE something fearful. Makes no sense.
The ego's basic mind-trick is avoidance of God, avoidance of the truth, avoidance of reality. But the thing is, it doesn't just avoid God. God is love. It isn't really telling you that you are avoiding love. If you knew you were avoiding love, and you remembered what love is, you wouldn't be willing to avoid it. So instead, it tells you you are avoiding something else.
The ego says, you're avoiding an evil God, and you wouldn't want to go anywhere near it. It tells you, you're avoiding real sin and guilt in the mind, and you shouldn't go anywhere near it. It tells you, you have a really big reason to be afraid because God is coming after you, so that you'll be justified in being afraid. All of this is designed to make you believe that you're actually doing the right thing by being in denial, or being afraid, or avoiding God, or going out of your mind.
The lie here is that fear itself INVENTS its own idea of what you are afraid of. And denial itself INVENTS its own idea of what you are denying. Once you enter into denial or fear, you're in a place of hallucinating and projecting ideas based in denial in fear, which out pictures God, or your mind's content, as also being fearful.
Here's the key. It's not that your mind HAS real guilt in it. It's not that you HAVE a real reason to be afraid of God. It's not that you HAVE sinned or that, if you looked within, you'd be confronted with the horrors of what you've really done. The key is.... ITS ALL A LIE!
There IS no reason to be afraid of God. There IS no real guilt in your mind. There IS no sin that you have accomplished. There is no dark icky content lurking for you to discover, to be ashamed or, or to feel bad about. THERE ISN'T ANYTHING THERE. You haven't really done anything. You haven't sinned. You're not guilty. THIS is what the ego does not want you to really FIND OUT when you look within. And this is what it DEFENDS against by telling you it is very justified in making you use denial and fear to protect yourself.
You're innocent. "What if you looked within and saw there was no sin?" - ACIM
So you have to realize this, the ego's devices of avoidance of God/Self/Mind all CLAIM that you should be afraid to look within, they all CLAIM that you've got tonnes of guilt to heal, they all CLAIM you sinned and that you would die if you faced God, but it's all a self-perpetuating myth. They're all lies. They're all defenses against the truth.
Ego defenses never defend you against the TRUTH, because they are designed to OBSCURE the truth, so that you believe you are defending yourself against something ELSE. You could never believe that defense against LOVE is ever justified - you can't hold an awareness of real love in your mind and at the same time believe you would ever not want it. So instead the ego tells you that there IS no love, its been replaced with something dark and sinister, and you need to defend against THAT - the God of hate that the ego made up (as itself).
So all the while you are fixated in your 'issues' about what you did, the sin, the guilt, the fear, all of that is designed to block and distract you from looking at what is BEYOND these things. Before sin there was separation, yes, but before separation there was LOVE. The ego doesn't want to you keep investigating what's real because eventually you'd unearth the love that you buried and realize it still exists AS love. And then it's game over for the ego.
The truth is, you are completely innocent and free. The truth is, when you look into your mind, you might AT FIRST seem to encounter guilt and fear and sin and shame and attack, but only because you still believe these things are real. They're just clouds of illusions. Temporary distractions. They're lies, all of them. Fear is never truthful. Denial is never called for. You don't need any defense from God because God is love.
All of these avoidances are really designed to cover up the ATTRACTION TO GOD which is so intensely powerful and undeniable that if you were to become aware of it, you would rush into God's arms and into eternal life immediately. It is this POWER that you attempt to cover up. It is this LOVE that you attempt to deny exists. It is this VALUE and MEANING that you try to stay away from by making up stories about what it's frightening. God isn't frightening, the ego is.
God is love.
