4 The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons. 2 Such teachings come through hypocritical liars, whose consciences have been seared as with a hot iron. 3 They forbid people to marry and order them to abstain from certain foods, which God created to be received with thanksgiving by those who believe and who know the truth. 4 For everything God created is good, and nothing is to be rejected if it is received with thanksgiving, 5 because it is consecrated by the word of God and prayer.

Paul then gives us two examples of the kind of teaching these hypocritical liars are guilty of, so we'll look at them one at a time: They forbid people to marry and order them to abstain from certain foods.

Why would they forbid people to marry?

God's plan from the beginning was that the two (husband and wife, man and woman) would become one, to create a family. The plan is that most of the time the two-member family will become 3, and then 4, maybe 5, and so on. "Be fruitful and multiply," the Lord said. In fact, the family became the central building block for society. The family is where people learn about their customs, their beliefs, their practices, and their relationships. As goes the family, so goes the world.
