You never seem to take notes on what you have told them, but I never heard of you forgetting anything you have promised them. Truth extends to honesty. If you are honest in all of your dealings, you never have to remember whom you may have cheated. Truth extends to encouragement. If you speak a positive truth about all people, you never have to avoid anyone.
Truth extends to implications.
If you refuse to give false impressions, you never feel the need to cover up. If you refrain from twisting the truth, you will never need to unravel a relationship gone awry. Live truth instead of professing it. The ability to lie is a liability. Truth supersedes belief.
