You were not constructed to live with anxiety.
Anxiety creates a different furrow than anger or regret. Anxiety is a form of fear that assumes there will be an unwelcome result of something yet to happen or not happen. The anxious Christian is living in the possibility that God does not know what is best, or in the alternative, that God will be too late or not perceive the situation.
The enemy loves to hurl fiery darts of anxiety into the mind and watch them fester.
Soldier of The Cross, we either agree with God or we don't. If we agree with Him no matter what, we are able to experience the solidness of the Rock of Ages.
The anxious Christian is desperately hoping God agrees with him - not the other way around.
Recognize it. Leave it at His feet. You can't operate under the load.
The One who gave Himself for you will gladly take it.
