Genesis 1:29-30
God said, “Behold, I have given you every herb yielding seed, which is on the surface of all the earth, and every tree, which bears fruit yielding seed. It will be your food. To every animal of the earth, and to every bird of the sky, and to everything that creeps on the earth, in which there is life, I have given every green herb for food”; and it was so.
Genesis tells us that it was God’s original intent in the perfect world for all creatures to be vegetarian; including mankind. To people, He gave all plants and fruit and to animals He gave all green plants. You shouldn’t go away now thinking that this is God’s plan for you today. There are many commands in the Bible that are no longer fitting for us as we learn as we move through the Bible. That’s why it is so important to not take Bible quotes out of context.
As the events of the world unfold, God also unfolds different rules. Some of the older rules are replaced or suspended for new ones under new conditions. As we read though Genesis, we learn why things changed. In my study of the Bible, I discovered that mankind’s relationship with God was to change as history moved along. God knew that things would be changing because the Bible says that He did. In fact, the Bible says that God already thought of you before He even started creating. God is quite a planner, but it is really outside of our understanding because God did His plans before time existed! (I am a creature of time so I don’t really know what that means.)
For very similar reasons, Christians no longer follow the Law of Moses. The conditions no longer exist for this set of rules. There is an extremely significant reason for this change too as we read the New Testament.
So, you shouldn’t try to be a vegetarian because of this verse. Later in Genesis, God will tell Noah that it is OK to eat animals after the flood.
