Leviticus 11 and 2 Corinthians 6 - I was trying to avoid comment

I'm tested here.

The dietary rules are clearly void today, but the separation doctrine still applies.

Read these two chapters in the KJV together to get the full teaching.

We do have this high point.

Lev 11:45  For I am the LORD that bringeth you up out of the land of Egypt, to be your God: ye shall therefore be holy, for I am holy.

Gill writes:

Leviticus 11:45

For I am the Lord that bringeth you up out of the land of Egypt,.... He had brought them out of it, and was now bringing them on in the wilderness towards Canaan's land, in order to settle them there; and this is observed, to show what obligations they lay under to him to observe his commands; for since he had done such great things for them, it became them to be obedient to him in all things: and the more, since his end herein was, as he observes to them, 

to be your God; to make it appear that he was their God, and they were his special people, whom he had chosen for himself above all people upon the earth; that he was their King and their God, to protect and defend them, to provide for them, and take care of them, and bestow all good things on them proper for them:

ye shall therefore be holy, for I am holy; separate from all others as he was, living holy lives and conversations, agreeably to his will made known to them, in imitation or him who had chosen and called them to be his people; for, since holiness is his nature, it becomes them who are his house and family, his subjects and people.

Note how Paul states the same.

2Co 6:16  And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.

2Co 6:17   Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you,

2Co 6:18  And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.

Btw verses 7-8 have an interesting twist.

2Co 6:7  By the word of truth, by the power of God, by the armour of righteousness on the right hand and on the left,

2Co 6:8  By honour and dishonour, by evil report and good report: as deceivers, and yet true;

Again Gill comments on Paul's fate...

As deceivers; for so they were accounted, as Christ was before them, by the unbelieving Jews, and by the false apostles, as if they were the authors, or abettors, and spreaders of errors, and the instruments of leading people aside.

And yet true; true and faithful ministers of the word; true to their Lord and master; true to the trust committed to them; true to the Gospel of Christ, and to the souls of men.

In today's world we can be confident we will have the same reaction from both unbelievers and even in the professing, visible church if we speak the truth.
