Working backwards in the emboldened sentences, the phrase - "I now give you everything" - implies that some things were withheld from the beginning into Noah's days. We see what WAS PROVIDED by observing what is said in the same sentence before the comma - "Just as I gave you the green plants,". God created us as vegetarians. Or maybe God created us capable of eating - "everything that lives and moves" as well as "green plants" and God just chose the time for the next phase of the human diet to be initiated.
I am finding that God's timing for things can be seen everywhere, if I would just pay closer attention to Scripture and even His workings in my life. Once again with this passage, if you read and observe the verse in italics the condition that God describes is future-present. This means it is getting ready to happen - "The fear and dread of you WILL FALL upon all the beasts of the earth...". We do not hear of this happening prior to this declaration by God. So, once again, this implies that at one time there was NO FEAR OF US upon "all the beasts of the earth....". It is all about God's timing again.
In previous studies concerning this passage I was passionate about it's meaning pertaining to the fact that we were all vegetarians at one time. This looks like a correct observation, but when the Holy Spirit led me back to it again this time He said - "do not worry, saying, 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?' For the pagans run after all these things, and your heavenly Father knows that you need them. But seek first his kingdom and his righteousness, and all these things will be given to you as well. Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own." Yep. These were the words I heard in my Spirit. Look familiar? They should. They are straight from Matthew 6:31-34. Do you notice what these words in Matthew are about? God's timing. From Old Testament to New Testament, God confirms there is a Holy Timetable and that I should trust in that.
