One of the 1st and Most Important Things you will ever need to focus 

your Time and Attention on, Is Getting and Keeping Your MIND under Control.

God Must Continually Be the Focus of Your Thoughts and Attention.

REMEMBER... The mind in the Bible Is Called The HEART.

and The Bible Says this about the Heart...

Jeremiah 17:9 (KJV) The heart is deceitful above all things, and desperately wicked: who can know it? 

The Bible tells us that the most difficult member of the body is the Tongue ...

BUT Even the Tongue is controlled by the Mind !!! 

Luke 6:45 (KJV) A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.

"The Mind" ... GET IT UNDER CONTROL !
