Be generous in the belief that God has a wonderful plan for you, and just relax, by being generous in the way you think positively about God.
Yesterday, I was in a situation that I was stressed about. My wife gave me an idea to ponder. "Craig, for this, try a new way of thinking. Instead of worrying/stressing over it, just keep saying, it'll be alright. Then, tomorrow you can go back to worrying/stressing, but for today, just choose and keep thinking, it'll be alright."
I confess that was a new way of thinking, and I can see the positive benefits of being generous in my thoughts by knowing, it'll be alright, because God loves me and has a wonderful plan for my life.
