You will guard him and keep him in perfect and constant peace whose mind [both its inclination and its character] is stayed on You, because he commits himself to You, leans on You, and hopes confidently in You.
Keeping your mind stayed on God = perfect and constant peace. When I allow my mind to go to my desires, my plans, my hopes and dreams...my anything...the peace leaves. When I am disciplined and keep my mind focused on God, He works. My plans are His and He has it all worked out and has already gained the victory.
I really wish it wasn't so hard. I went to work this morning praying that my mind would be stayed on God. The reality was that I barely thought of Him all day. I thought about the MRI I didn't want to do. I thought about how busy I was at work and what I didn't like about my job. Really what I thought about was me. I got mad at Craig for not calling me and asking me about the MRI. I felt sorry for myself and was only inward focused.
Peace really is a beautiful thing. I love the scripture in the Bible that calls peace from God something the world does not understand. That is so true. Sometimes I think I'm getting a handle on it and then days like today happen and I wonder if I've even come a step or 2? So...out of necessity...I think I am going to be working on "staying". Come on Peace:)
