It is when I am in the nature that God created and all is still that I sense the overpowering presence of the living God more than ever. Truly He is almighty, Sovereign, and knows your heart. Walk in the spirit and you will overcome the fears and doubts of the flesh. Start thanking God for all that He made and for what He has done in your life and surrender all of your circumstances to Him and the anxiety will flee. Realy do this, it works every time!
