'Ruin' in the Bible

So I say, have they stumbled so as to fall [to spiritual ruin]? Certainly not! But by their transgression [their rejection of the Messiah] salvation has come to the Gentiles, to make Israel jealous [when they realize what they have forfeited].

If your brother is being hurt or offended because of food [that you insist on eating], you are no longer walking in love [toward him]. Do not let what you eat destroy and spiritually harm one for whom Christ died.
