Why not? Because they pursued it not by faith but (as if it were possible) by works. They stumbled over the stumbling stone,

and a stumbling-stone and a rock to trip over. They stumble because they disobey the word, as they were destined to do.

just as it is written, “Look, I am laying in Zion a stone that will cause people to stumble and a rock that will make them fall, yet the one who believes in him will not be put to shame.”

Do not destroy the work of God for the sake of food. For although all things are clean, it is wrong to cause anyone to stumble by what you eat.
