Ephesians 4
16 from whom the whole body, joined and knit together by what every joint supplies, according to the effective working by which every part does its share, causes growth of the body for the edifying of itself in love.

If one part does not do it’s job, there is no effective growing. As a body, we MUST be working together. We must have the same common goal and be working towards it for the good of those we are trying to minister to.
