Every day we are all in a fight, it is the battle in our minds.  It is not a natural battle that we are in, but it is a spiritual battle.  The enemy of your soul, the devil, wants to discourage you, deceive you, cause you to fear for your future.   And the reason he does this, is to keep you away from God's will in your life.  But if you will prepare yourself daily to stand, keep your eyes on Jesus, and you do not quit - you can win the battle of the mind.
