We have to learn to maintain our rest.
Today as I was meditating visually, a lot of things would come upon the screen of my mind, that I was not sure was of God. I noticed it was disturbing my peace, so I did not meditate on them.
I seem to be more at rest when I close my eyes, than when I have them open. But I can only see in the spirit, when my brain waves are Alpha (right before sleep) than Beta (When I am wide awake).
But I need to be wide awake, to do certain things.
I am a faith preach that (no one knows), so I have financial problems, not enough money to do certain things I need to do, and also the burdens of Christians in my heart, so I have to keep casting them on the Lord and maintain rest.
As Christians, we should be incredibly peaceful, tranquil, and calm. 
The enemy cannot penetrate the armor of a person at rest in God. As God’s beloved, part of our inheritance is complete confidence in Him. This confidence in His nature puts our spirit at rest.
Spend some time with God and just relax and rest in who He is for you and all His promises and provisions for you.
See how your feel doing that, compared to the rest of your day.
