Read Proverbs14:5  Solomon is reminding us that someone who is faithful will not let you down.  If they are honest and trustworthy with you, they will be honest and trustworthy with other people as well. When they give a witness in court, they will always tell the truth.  That is because they are an honest person inside.  But a dishonest person is dishonest on the inside.  And they are dishonest when they can get away with being dishonest.  They will pretend that they are cheating for you.  They will whisper to you and say, “Boss, I worked hard for you today and made you extra money.”  That means that they must have cheated other people to get more money for you.  But, if a dishonest person will cheat someone else to get you more money, later, they will cheat you in order to get more money for themselves.  The reason is that a dishonest person is always dishonest.  They may be your friend and be honest with you for a while, but eventually, when it suits their need, they will cheat you too.  That is because they are a cheat and dishonest on the inside.  What are you like on the inside?  Are you truthful?  Will you lie or cheat?  Remember, God sees your heart.
