ROM 14:23

23 But some believers are not certain [that God will approve of their eating a certain kind of food]. So if they eat it, [they think that God will punish] them. And they [truly] will be punished {[God truly] will punish them}, because [they have done things that they] believe [are not right]. Those who do anything without being certain [that God considers it to be right] are sinning.
