We simply cannot ignore that Peter's protest about eating what was in the sheet and subsequent confusion about the true meaning of the vision is evidence that he knew whatever God was trying to show him had nothing to do with diet. Eventually, in the same chapter, he tells us plainly what he finally understood to be what God was showing him, confirming that it had nothing to do with diet: "God has shown me not to call any MAN (not beasts) common or unclean." It was God revealing to him that it was not time to take the Gospel to the Gentiles like Cornelius. Isaiah 66 is a prophecy of Jesus' Second Coming with fire and destruction in which Isaiah says that those eating swine, mice, and other such abominations "will be consumed together".Daniel 10 describes a fast that Daniel and his friends took in which they were much healthier than the kind and his servants.
Acts 10 says that there is no unclean thing, from a religious point of view, but nothing is said about the health implications. Simply that no foods are forbidden.
I like your avatar name. Is that a reference to when a converted soul steps down from the throne of his heart and allows Jesus to take His rightful place?Romans 8:32 (KJV)
He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?
