We know things. We know that the bible tells us to pray and that we are supposed to offer up worship to God. We may know all of these things yet many of us are unchanged. Why is this?
If we know the keys to heaven and yet our hearts remain the same, I feel there is something we don't have.
Revelation.
If we know things our mind is enhanced. If we have a true revelation of things than our heart becomes aware and changed. Without revelations of Kingdom truths, our hearts will remain the same and we will have no urgency for what it is we "know". Revelation is something that will give our hearts a new understanding and our entire characters will no longer act the same. With knowledge nations can think. With revelation nations will be changed.
