It’s been stated that when David wrote, “Yea, though I walk through the valley of the shadow of death, I will fear no evil,” he was in a place where evil was an ever-present reality. Yet he refused to give in to fear. He wasn’t under any ideology that God would abolish evil, so he could pass through the valley safely, No, he was saying that the presence of God with him, gave him the confidence to pass through difficult places without fear of God deserting or leaving him.
