1st Principle of Worship

What is the first principle of worship? The 10 Commandments tell us not to make any graven images, bow down to or serve them (Exodus 20, Deuteronomy 5). Does that forbid art work, pictures and statues? God instructed Israel to embroider pomegranates and cherubs for the Tabernacle (Exodus 26, 28, 36, 39), cherub statues for the mercy seat (Exodus 25, 37) and a bronze snake on a pole (Numbers 21). These pictures and statues were not idols. They were not to be worshipped. Israel DID later worship the snake and so it was destroyed. Therefore, the first principle of worship is that we do not bow down to, nor serve anything or anyone in place of God (Deuteronomy 6:13).
