Notice the overwhelming emphasis on the holiness of God. The priests, the clothes, the tabernacle, and the sacrifices had to be clean and consecrated, prepared to meet God. In contrast, today we tend to take God for granted, rushing into worship and treating him with almost casual disregard.  But we worship the almighty Creator and Sustainer of the universe. Remember that profound truth when you pray or worship, and come before him with reverence and repentance.
