👉 The word "Crystal Rock" in Scripture refers to a rock that appears transparently, but is not made of any substance like glass or obsidian. This term has been interpreted as indicating an unalterable state or condition. It was once mentioned by Jesus Himself when he referred to rocks which appear so clear and perfect, they are "crystal-clear" (Matthew 16:27). In the New Testament, it's also used metaphorically as a reference to spiritual purity or purity of heart.
