The focus of the Tabernacle/Temple of Israel is the Ark of the Testimony, aka the Ark of the Covenant. That’s a key lesson of the Torah reading תְּרוּמָה Terumah (“contribution,” Exodus 25:1-27:19). The Ark protected the founding documents, the constitution of the People of God. This document binds all the people of God together, just as the people of the United States are bound by the U.S. Constitution, honor that document and work to put it into practice.
Heaven put the Word of God into action in the midst of the people of God with the birth, ministry, death and resurrection of Yeshua the Mashiakh (Jesus the Messiah/Christ).
If the people of God don’t put the 10 Commandments into practice, we run a real risk of losing our first love and going astray from God. We can end up in a very bad place. When we realize we have gone astray, the first thing we do is to turn back to the foundation.
