There are a couple scriptures that I turn to in case of well needed encouragement. I am in the procss of turning feelings into simple emotions... instead of the mood enhancers I've often given them credit of being. I found this task to be one of somewhat difficulty when I'm thinking on and dreading over things I cannot control (and frankly have no place trying to control).
The following scripture has changed the way I approach my wandering thoughts. I keep them in check and don't let them have any room or any vote of their own.
It is also a little hard at times of financial struggle to not worry about where the food will come from, or the gas that's needed to get to work, or even having a job itself. This scripture has become somewhat of an anthem for my life. It has opened my eyes to how important I am to my Father and Creator. He cares about me and He will always provide!
I truly hope these scriptures bring some encouragement to you. Worry and anxiety are things that are running rampant lately and destroying the happiness God intended us to live in! So SMILE! Think LOVELY things and keep your eyes on the sky, fixed upon the One who feeds the birds.
