God has commanded His people to keep themselves from certain things such as pork, also known as, swine's flesh.
There is one verse that tells me God still commands His people to obstain from pork and it's found in Isaiah. This verse is speaking about the last day when the Lord returns to destroy the wicked. Listen to what it says about those who eat swine's flesh.
Isaiah 66:15-17 For behold, the Lord will come with fire and with His chariots, like a whirlwind, to render His anger with fury, and His rebuke with flames of fire. For by fire and by His sword the Lord will judge all flesh; and the slain of the Lord shall be many. "Those who sanctify themselves and purify themselves, to go to the gardens after an idol in the midst, eating swine's flesh and the abomination and the mouse, shall be consumed together,'' says the Lord.
It's hard to get around this verse because it's speaking of the endtime judgment.
