Stress leads to confusion. What happens next is what determines whether you know peace or experience more stress. Stress is a part of life. There is no way to avoid it. But what you can avoid is the pain and disorientation of continuing stress. In the midst of confusion you can either turn to God and his word or you can rely on your own judgement and watch the stress and confusion grow. Trust in God and his ways leads to peace. Like oil and water, trust and stress do not mix (See Matthew 6:19-34). When you attribute short, curt answers and a contentious spirit to stress, you are demonstrating that the stressful situation has overcome you. There is much in life that can be overwhelming. But God remains in control of his world. We don't have to be driven by worry. With all that Job experienced, he was not dominated by worry and stress.
Proverbs 3:7-8 indicate that our bodies don't do well when we trust ourselves, that is, when we rely on our own understanding. Trusting God and purposely loving him in all that we do brings health to our soul and stability to our walk. Trusting our own understanding leads to a troubled spirit, to a lack of stability and to more stress. Loving God in every area of your life means an intentional awareness of loving him.
