Proverbs 22: 11 He that loveth pureness of heart, for the grace of his lips the king shall be his friend. 

Graciousness is the most beautifying character. A gracious person is often described as a beautiful or charming person. Whether man or woman, graciousness makes a person delightful, pleasant, and winning. It is a rare and sweet pleasure to meet one. And this trait is most clearly shown by excellent speech. You will meet only a few in life; they will have great reputations; they will warm your soul; and you will crave their company. Graciousness begins with a pure heart. A man's speech simply reflects his heart (Luke 6:45), so you must keep your heart with all diligence (4:23). If your heart is cheerful, contented, forgiving, kind, and thankful, you will think gracious thoughts. You must reject all sinful thoughts of bitterness, envy, evil surmising, malice, or revenge.

 
A pure heart produces gracious speech. Paul said, "Let your speech be alway with grace" (Col 4:6). He told the Ephesians to avoid all corrupt speech and focus on words that build others up; he said that a tenderhearted spirit based in kindness and forgiveness was right, but that bitterness, wrath, malice, and evil speaking were wrong (Eph 4:29-32). If you think kindly about others, rule your spirit, and guard your tongue, you will be gracious!
