Bill there is a lot of ways to tell a lie. Some are outright and some are veiled to slander or sway others. Just about every way to tell a lie is done on this BB and even done by some Mods, and administrators or at least sanctioned by them by turning of their heads when reported.
As said above, lie and truth come from inside, a motive of the heart. Truth can be used to hurt someone to the core. Many comments about physical appearance, smell, cleanliness, for example could be told to a person as the truth, with the intent to hurt their feelings. So what has been accomplished by telling the truth? Sometimes things are best left unsaid.
On the other hand, lies can be told be not saying anything. It is the intent of the heart, in a Christian, a Christ filled heart. There are examples in the Bible of untruths being used in the Lord's purposes, such as the actions of Rehab, a person of great faith that made the rolls in Hebrews 11.
In practical living, I am guilty as the next person about not saying things at times. For example, while I worked, I knew of several guys cheating on their spouses, some working right in the same building. If you think I was about to go up to the wife and tell her, not me. If it is a sin, then the Lord will forgive me.
At the same time, I am not about to go up to someone who is not the most attractive thing on earth and make fun of his or her physical feature, although what I would say is the truth. Another thing I will not do, from experience, is when in a crowd, restaurant, etc, and hear foul language, with my family, I will not confront the people saying it. Good way to get shot. I remove us from the area.
I consider gossip one the the most destructive sins running rampant in the church today. I know people who salivate at news about another member or family member who is caught in some kind of sin, a trial or other hard situation. If I know about it, and someone asks me for details, I ask myself, does this person want to pray for this brother or sister in Christ, or are their jaws going to start flapping, and they get an adrenaline rush from the situation. Ninty percent of the time it is the latter.
