A few four-letter words essential to the Christian:

LOVE God with all your heart, and your neighbor as yourself.
GIVE cheerfully, not grudgingly.
LIVE today as if it were your last on earth.
LOOK for the best in people.
KIND words never die; neither do harsh ones.
PRAY without ceasing–it works miracles.
WORK while it is day; the night is coming when no man can work.
OBEY God. It is better than sacrifice.
HOPE for better days and peace eternal.
