Revelation is not an endless pursuit of mystery, it’s an ever deepening relationship through which God glorifies himself and moves through you with your collaboration.
Revelation is two-fold; it comes when you have placed attention, time and study in an area and increased your knowledge and understanding. God will use that knowledge to enlighten the eyes of your heart so you are persuaded in faith and it moves beyond just information. Then God helps you understand how to wisely apply that revelation.
Ultimately, revelation is when you see God’s glory, meaning you see things like he sees them.
The reason you don’t allow yourself to receive revelation is because you don’t have the intention to act on what’s being revealed, you won’t let yourself see it. When you are willing to yield to his will, the truth you need will no longer be covered.
