syn·er·gy (sĭn'ər-jē) n. : The interaction of two or more agents or forces so that their combined effect is greater than the sum of their individual effects.

When we combine our efforts in submission to God's will, He takes those efforts and multiplies them according to His desire, resulting in something far greater than we could have accomplished on our own.  This is what we mean when we say synergy.

(You+Me)Christ=Synergy
