Eating unclean animals DEFILES us and makes us UNCLEAN (Leviticus 11:43-44).
Our body is the temple of the Holy Spirit. If we defile it, or make it unclean- the Holy Spirit will flee from us and God will destroy us (1 Corinthians 3:16-17). The Holy Spirit will not ever reside in a defiled or unclean house. And God would never destroy a temple that is occupied by the Holy Spirit.
We are told that nothing unclean will enter God’s Kingdom (Ephesians 5:5).
Isaiah’s prophecy says that when Christ returns, He will destroy those who eat pork and other unclean animals (Isaiah 66:15-17).
And Christ says that every prophecy concerning him will come to pass. So according to Christ, Isaiah’s prophecy IS coming true because it’s about him (Luke 24:44).
A person who’s ignored and is defying God’s dietary Law by eating unclean animals as a fixed- or an integrated part of their daily life or living, is “practicing” lawlessness (A disregard for God’s Law). And Christ will say, ” I never knew you; Depart from me, you who practice lawlessness” (Matthew 7:21-23).
