All of life is relationships. Without a doubt the greatest destructive factor in any interpersonal relationship is a lack of trustworthiness. There is no way to dress it up.People who lie, shade the truth or tell only a half truth not only reveal a total lack of self-respect but demonstrate a lack of respect for other people as well. Trust is a cornerstone of any meaningful relationship. If you do not trust me there is no firm ground on which to build. The Bible calls this building your house on solid rock. In the story of the three little pigs, it is the house built of bricks. Lasting interpersonal relationships need both a firm foundation and solid building materials.
