If you church teaches dress and behavior standards that you must abide by in your own personal life, while not at church, they have made new Laws of salvation. This is legalism at its purest and darkest form.
God is Holy. We are to strive to be like Him. We worship in the beauty of Holiness. Yet – what is it? Some say its a dress standard. Some say it is a spirit or heart condition. Could it be both? Does how you dress or behave make you Holy, or is it having the Holy One dwelling in you?
