Therefore, having put away falsehood, let each one of you speak the truth with his neighbour, for we are members one of another.
Ephesians 4:25
We always encourage everyone in school to tell the truth. Long-gone are the days of 'your tongue'll go black if you lie'(well that's what I was told!), instead we demonstrate the benefits of being honest and owning up - and this has links with respect and responsibility too.
Pictures of honesty and truthfulness are hard to find, as it is a quality difficult to quantify. So when we find some, we'll post some (honest).
