If you consider omission a type of lie, then everyone lies - especially the Christians. I mean, it's not Christian behavior to say mean things to others so you omit saying them - even if you think them! However, if you do not consider omission a lie, then it is possible to live a life without lying (I do!). Say, for example, a friend asks how a dress looks on her and you think it's not flattering, then in order to tell the truth, you tell the truth. Perhaps it's a good color for her so you say, "Hey! That's a great color on you!" That's not a lie but the omission factor... that will depend on how you personally define omission (a lie or not a lie... that is the question). The only time, in my opinion, that it's okay to lie is when your life is endangered - like to a nutcase. For example, I once worked with another girl at a store and we were robbed by two people on drugs. One guy took a knife and held it up to the girl I worked with and asked me where the money was. I said the money was in the register. I did this because, even though there was money in the safe, we had no way to open the safe. If he didn't know there was a safe, it wouldn't be an issue. I gave him all the money in the cash register and they took off! That, to me, is an okay time to lie... but technically, it was omission... so was it a lie after all? You can decide, based on your opinion of omission.
