Proverbs 22:1

A Good name (earned by honorable behavior, godly wisdom, moral courage, and personal integrity) is more desirable than great riches; and favor is better than silver and gold.  

Trust from people is based on our behavior and being trustworthy ourselves—our decisions in public and private show in our character.  Everyone should strive to have an honorable, reliable character because God can use a person like that to do His work here on earth.
