Two requirements for happiness in this life.

Psalm 34:12-13

12Does anyone want to live a life

that is long and prosperous?

13Then keep your tongue from speaking evil

and your lips from telling lies! 

1 Peter 3:10

10For the Scriptures say,

“If you want to enjoy life

and see many happy days,

keep your tongue from speaking evil

and your lips from telling lies.
