At this time, Paul was addressing people who worshipped pagans. In their religion, the gods lived in those statues/shrines. In idol temples, the preists often bring food and other necessities to their gods.
Jesus does not “live” in the tabernacle - He is there, and He is everywhere. He also gave us Himself through the Eucharist in a different (no flesh, sacramental) way, so wherever the Eucharist is, He is there.
