I have been called and I have been called by none less than Christ. He called me out of this world.
The modern translations always choose a word like behaviour, and that is all right but the Greek word isn't well translated by behaviour. The Greek word comes from a combination of words which mean in your to-ing and fro-ing – ‘Be ye holy in all manner of to-ing and fro-ing.’ The word is derived from this idea of interaction with others. Nevertheless it does include behaviour; it’s not just talk. It’s about how you talk to other people, and how you react to other people: it’s all of it. In all manner of conduct towards other people: towards believers, towards unbelievers, towards people we should respect who are above us, towards children to whom we set an example and instruct. In every kind of interaction we are to be holy. It is a massive exhortation. Every interaction in trade and business is to be marked by courtesy, holiness, good temper, and goodwill.
