The reason is that truth is a fundamental aspect of our soul which was is part of the Godly essence that was given to us. The verse in proverbs "Truthful speech abides forever,  A lying tongue for but a moment" explained by Rabbenu Yona tells us that one who is always careful with his words to speak honestly will always be abided and desired because we have a natural connection and love for truth.Shaarei Teshuva אמרו רבותינו זכרונם לברכה אסור לגנוב דעת הבריות. והנה החטא הזה חמור אצל חכמי ישראל יותר מגזל יען וביען כי שפת שקר אשמה רבה. ונתחייבנו על גדרי האמת כי הוא מיסודי הנפשMishle שְֽׂפַת־אֱ֭מֶת תִּכּ֣וֹן לָעַ֑ד וְעַד־אַ֝רְגִּ֗יעָה לְשׁ֣וֹן שָֽׁקֶרPlease send any feedback for any of the episodes to [email protected]
