"...with all my heart and soul."

       "And to love him with all the heart, and with all the understanding [mind], and with all the soul, and with all the strength, and to love his neighbor as himself, is more than all whole burnt offerings and sacrifices."

~ Mark 12:33 (emphasis added)

There are four channels of love.

Heart ~ Our emotions

Soul ~ Our will and general individuality

Mind ~ Our intellect

Strength ~ The activities and energies of our service

 "Often we cannot feel love, but we can always use our strength for God and show our love by doing things which we would never do except for his sake."        

~ from F. B. Meyer's Devotional Commentary (emphasis added)
