" But we still must tremble before our God. He is still holy. Our trembling is the tremor of awe and veneration, not the trembling of the coward or the pagan frightened by the rustling of a leaf. Luther explained it this way: We are to fear God not with a servile fear like that of a prisoner before his tormentor but as children who do not wish to displease their beloved Father. "
