Keeping Truth a Secret?

The occult is based on secrets and "hidden" knowledge. The Bible teaches that "everything hidden shall be revealed." Unlike the "god of this age", "the father of lies", and "the great deceiver" (how Satan is described in the Bible), the God of the Bible is the God of LIGHT. He exposes and reveals secrets. I was speaking to a friend about this tonight and these verses came to mind, especially pertaining to the way a church functions (when deacons/elders keep secret, ungodly decisions from church members). We must remember that Jesus is the head of the church, not people.
