What did worship look like in the beginning?

• Between The Fall and The Flood, we get a limited amount of information about what was actually happening worship-wise
• No formal instructions seem to be given
• There had to be some sort of law however, because sin existed.

Examples of "law" before it was written

• Sabbath (Genesis 2:2-3; Exodus 20:8-11) => The Sabbath was made Holy at creation and the Israelites are commanded to remember the Sabbath
• Murder (Genesis 4; 9:6) => Cain is warned that sin is at the door when he is angry at Abel and God punishes him for the murder. Murder as a sin is explicitly stated after the flood
• Food Choice (Genesis 2:16-17; 7:2; Leviticus 11) => the first law ever given
• Sacrifices (Genesis 8:2; 22:9; 26:25; 33:20

People who are descended from Abraham but not Israelites follow the Most High God. There are also people not descended from Abraham that follow God.

• Ishmael, Abraham's first son, is thought to be the progenitor of Islam. Though different than the Biblical definition, they also have clean and unclean meats and a dietary law they follow (Halal).
• Moses' father-in-law is a priest and a descendant of Midian, one of Abraham's son's from Keturah after the death of Sarah.
• Melchizedek

Remember, people raised in the same house can take different beliefs into their adult lives. Our personal experiences shape our perception along with what we are taught. This is why there are similarities (and differences) in the religions of the world. All of these people can trace their origins back to Noah, and thus Adam.
