I am thankful that animal sacrifice is not needed for atonement for sin, but some animals will always be a source of food. I never been on a farm, I have always lived in the city, but my 14 yo daughter and I are archery hunters, and fresh water fisherpersons, we know the fruits of our labor, plus we enjoy the great outdoors that God created for us to enjoy, it is good healthy living when in balance with fruits, vegetables, bread and fellowship. There is great satisfaction in having the knowledge of providing for ourselves, I believe it is a comfort that the Lord wants us to have. My daughter and I pray for the Lord to grant us successful hunts, and just after the harvest of our game, while our hearts are still pumping from the excitement of the hunt, we get on our knees after we find our downed animal and give thanks for the food. And taking care of the harvest animal, field dressing, skinning and quartering up is not a big deal when you know and understand the Lords grace overall of your entire life.
A pastor told me once, that most people don't know that if they where to go 12 mealtimes without food, they wouldn't hesitate to kill for food, a natural instinct to survive, it would be on your mind every minute your awake.
