Phil 1:27 '...that you stand fast in one spirit, with one mind striving together for the faith of the gospel.'
Unity only happens when we are united in the same purpose! It takes work to remain connected in the same 'attitude', 'spirit.' When we are disconnected without unity, harmony & alignment we are powerless. The church's effectiveness rests on her united-ness. The great common goal that transcends all other concerns we may have, is bringing people to Christ, so they are born again. This is our great unifying cause & needs to be the purpose of every local church. When we strive together for the salvation of our world the power of a united spirit powered church will transform nations.
