The presence of God can be a terrifying thing. How much more terrifying when we realize that we stand before him completely exposed and laid bare. Naked. There is nothing that we can hide from his all-seeing eyes. He knows every thought, every intention, every motive.
Standing completely naked in front of someone is one of the most fearful things you can do. Today, the world has cheapened nudity and sex, making them commodities to consume. Even so, for just about everyone, one of the most frightful and scary things you can do is to stand naked before someone, waiting for that one person to accept you for who you are.
I was a virgin when I got married, and I still remember how I felt on my wedding night (besides horny). For the first time in my adult life, I was going to stand before someone completely naked not attempting to hide anything. I remember how self-conscious I was because I had recently been through a surgery in a sensitive area that left a scar and changed the way my body looked. But as terrified as I was, I also remember feeling safe. I knew that the woman I married accepted me unconditionally and that she would never turn away from me or leave me. Marriage made it safe. That's why I don't understand the current mentality where people basically sleep with whomever they want. Sex has become more a part of the dating ritual rather than something to be experienced in the safety of marriage. Unconditional love and acceptance aren't even in the picture. True intimacy (as opposed to just sex) requires unconditional love and acceptance. I can be truly intimate with my wife because I know that there is nothing I could do that would make her leave me. She's in this thing for the long haul. Therefore, I'm uninhibited in my intimacy with her and she with me. Even sometimes today, true intimacy can be scary, but it's safe because of our relationship.
I don't think it's a coincidence that Scripture likens the relationship between Christ and the Church to the marriage relationship. The church is the bride of Christ. In the beginning, Adam and Eve had this perfect, uninhibited relationship with the God of the Universe, but sin screwed everything up. Once sin entered the picture, standing before God in his presence became a frightful thing. That relationship was marred, and all of history ever since has been about repairing and restoring that relationship. That's why Jesus came. And that's why we don't have to hide anymore.
It's no less of a terrifying thing to stand before him knowing that we are completely exposed, but in Christ it's safe. If you are a follower of Jesus you are the bride of Christ. Your sin has been dealt with, forgiven, and forgotten. You are accepted unconditionally and there is nothing you can do that will make him turn away from you or forsake you. You are loved. You are accepted. It's time to come out of hiding.
