Yea, though I walk through the valley of the shadow of death, I will fear no evil; for Thou art with me (Psalm 23:4).
In the battles of the marketplace, your peace is actually a weapon. The marketplace creates many opportunities to rob of us our peace. Cash flow concerns. Deadlines. Relationships. All create stresses on us. Your confidence in the God of peace declares that you are not falling for the lies of the devil. You see, the first step toward having spiritual authority over the adversary is having peace in spite of our circumstances. When Jesus confronted the devil, he did not confront Satan with His emotions or in fear. Knowing that the devil was a liar, He simply refused to be influenced by any other voice than God's. His peace overwhelmed Satan, His authority then shattered the lie, which sent demons fleeing.
There is a place of walking with God where you simply fear no evil. David faced a lion, a bear and a giant. In this psalm he stood in the "shadow of death" itself, yet he "feared no evil." David's trust was in the Lord. He said, "...for Thou art with me." Because God is with you, every adversity you face will unfold in victory as you maintain your faith in God! David continued, "Thou dost prepare a table before me in the presence of my enemies." The battle you are in will soon become a meal for you, an experience that will nourish and build you up spiritually. Only God's peace will quell your fleshly reactions in battle. The source of God's peace is God himself. If fear has been knocking at your door, begin to face that fear with God's peace. It is God's secret weapon to destroy fear.
