Being unequally yoked dating
Using the OT principle of preserving boundaries between things that should not be mixed, Paul simply says that being Christian means that the Corinthians can no longer practice the activities of pagan worship or pagan ethics, since those are things that should not be mixed with the worship of God.
In other words, what they did ethically mattered a great deal if they were claiming to be Christians.
Or what fellowship is there between light and darkness? For we are the temple of the living God; as God said, "I will live in them and walk among them, and I will be their God, and they shall be my people.
17 Therefore come out from them, and be separate from them, says the Lord, and touch nothing unclean; then I will welcome you, 18 and I will be your father, and you shall be my sons and daughters, says the Lord Almighty." The background of this verse comes from an Old Testament instruction in Deuteronomy: You shall not plow with an ox and a donkey yoked together.
It was not just a legalism, but an attempt to live out in all aspects of life what they understood to be God's purposes for his world that he had created.
Paul, trained Pharisee that he was, no doubt well understood all this and applied this principle in addressing the church at Corinth (2 Cor ).
The idea of separating and setting boundaries, even among plants and animals ("each after its kind"), expresses the idea that there is a certain way God's world should work, that there are certain boundaries and limits within which creation can exist (see God and Boundaries).
For what partnership is there between righteousness and lawlessness? 16 What agreement has the temple of God with idols?This occurs between two similar commands about mixing things. You shall not wear clothes made of wool and linen woven together.22:9 You shall not sow your vineyard with a second kind of seed . These religious laws are connected to the creation account in Genesis 1 in which God established an order in the world that is part of creation itself.The result is a lifestyle that is "cleansed" from such contamination with pagan practices as visiting temple prostitutes (2 Cor 7:1), because someone who truly loves God as a son or daughter would not contaminate themselves with such practices.In others words, Paul is simply answering that it does, indeed, make a difference what the body does since that cannot be separated from who we are as sons and daughters of God.
