For The Lord Is My Tower 
[ Tab from: http://www.guitaretab.com/m/misc-praise-songs/204456.html ]
                     G
For the Lord is my tower
                      C
And He gives me the power
    G                            D 
To tear down the works of the enemy
                 G
In a difficult hour
                      C
He will crush and devour
                G               D              G
And bring the power of darkness underneath my feet
