Did God really say I could not eat shrimp?
Yes … yes he did.
What God said was: “Of all the creatures living in the water of the seas and the streams you may eat any that have fins and scales. But all creatures in the seas or streams that do not have fins and scales you are to regard as unclean. And since you are to regard them as unclean, you must not eat their meat. Anything living in the water that does not have fins and scales is to be regarded as unclean by you.” Leviticus 11:9-12
Shrimp, crab, lobster, oysters, clams, scallop etc … these creatures are “bottom-dwellers” and the sea’s garbage collectors. God established dietary laws for the Israelites in part to separate his people and make them holy. Separate yourself to him. Invite his Holy Spirit to dwell within you. Become a fisher of men.
