Day 38...(Exodus 25,26; Psalm 38)..."Origins of Worship"

In moving into chapter 25 and 26 of Exodus, Israel continues tangible ways of spiritual formation. After the formation of the Ten Commandments, a tabernacle and ark are constructed in intricate detail. According to NIV study notes...Tabernacle means the "Dwelling Place" and the ark sybolizes the "throne of God." The reading takes on different meaning as I recall there is no "cross", Bible, communion, and the core tenants of worship. Are these chapters not the structured beginnings of Israel's need to have focal points for worship? Can we not find some of the origin or humankinds need of symbols, symbolism, and worship?
