1 Corinthians 6:12 All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any.
We have come a long way since the law was given. Man has evolved beyond the demands of the Mosaic law.
Leviticus 11:7 And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he is unclean to you.
This is the best known of the unclean animals of Leviticus. Some religions still adhere to abstaining from eating pork. I live in BBQ country and have no such objection. There are many unclean issues given in the bible and they are not all about food.
Scientifically we have discovered that all these instructions were meant to keep us safe and healthy. We have gained in knowledge and there is no need for us to abide by these commands, we have evolved. The intent of the law to keep us safe and healthy is no longer required. We are bigger, faster, and stronger than ever. Just look at our pro athletes.
God provided for our safety when we were ignorant of the dangers surrounding health. Not all His command were given for health reasons. I can see picking and choosing which health commands to ignore. Others pick and choose what commands to ignore because they are no longer desired. This is a mistake, but it happens. Give people the liberty to say “all things are lawful” and they soon ignore what is and is not expedient. Paul’s reference to that in 1 Corinthians 6 was in relationship to the goal, the end game.
Godly wisdom is required to make those distinctions.
In rereading your post on evolved bodies after reading about the soul and spirit, I couldn’t help but think of Acts 10 vs 13 through 15 where Peter has the vision on the housetop and the voice speaks to him “rise Peter, kill and eat, for what God has cleansed, call thou not common or unclean”. God has provided for our body nourishment, but sadly this can become an obsession as in Philippians 3:19 “whose God is their belly.”
Ron that is a spiritual answer. appetites of the flesh they are called, but not of the body as such. Lust is more emotional than physical but the system of enactment, how it is played out is physical. Some go as far as blaming the body system, hormones for sin. Jesus had a body same as ours, tempted but did not sin. The expressions used can lead us to look to our appetites as being “not my fault”. While they are natural, they are not responsible for the act. Our souls are responsible.
