Disallow stress by keeping your focus on the best you can be for God. Peace and tranquil surroundings will easily flow in your presence by your thinking.....
"Let him eschew evil, and do good; let him seek peace, and ensue it." 1 Peter 3: 11 KJV
Think on this:
I will think of peace in the Lord, and the tranquility of his Holy presence will be at my daily rest.
