So I read Alma 2 today and the closest thing I could find to a good scripture quote is
And it came to pass that Alma, being a man of God, being exercised with much faith, cried, saying: O Lord, have mercy and spare my life, that I may be an instrument in thy hands to save and preserve this people.
Now when Alma had said these words he contended again with Amlici; and he was strengthened, insomuch that he slew Amlici with the sword.
Not exactly a feel good quote... So I have this quote from Ezra Taft Benson.
"Forget yourself and find someone who needs your service, and you will discover the secret to the happy, fulfilled life."
That's a little better.
