Romans 9:32-33

9:32 Why not? Because they pursued it not by faith but (as if it were possible) by works. They stumbled over the stumbling stone, 9:33 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.

Romans 14:20

14:20 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.
