We examine many scriptures showing God regards sins of knowledge (knowing what we're doing is wrong) far more seriously than sins of ignorance, or unintentional sins. A good Pre-Passover examination. We discuss: how often in fact we sin with full knowledge of what we're doing; how to put the real leaven of sin out of our lives. Really overcoming sin, really changing. "Casual sin", sins done in defiance. We hope Passover means more after this message.
