But whoever has doubts about what they eat is guilty if they eat. That’s because their eating is not based on faith. Everything that is not based on faith is sin.
One person considers one day to be more holy than another. Another person thinks all days are the same. Each of them should be absolutely sure in their own mind.
But not everyone knows this. Some people still think that statues of gods are real gods. They might eat food sacrificed to statues of gods. When they do, they think of it as food sacrificed to real gods. And because those people have a weak sense of what is right and wrong, they feel guilty.
To people who are pure, all things are pure. But to those who have twisted minds and don’t believe, nothing is pure. In fact, their minds and their sense of what is right and wrong are twisted.
Without faith it is impossible to please God. Those who come to God must believe that he exists. And they must believe that he rewards those who look to him.
