John M. Perkins said this quote

“ Right before Jesus went to the cross, He prayed that all believers, past, present, and future may be one, as You, Father are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me (John 17:21 NKJV). This was Jesus's prayer for us all, yet more often than not, I fear we have not lived up to it. Instead, we fight for our own way, for our selfish desires, for our right to be superior. We build churches centered on our own cultural ideas of God, rather than on seeking to bring us back to Him. And then we fight with other churches and religions about who is serving their personal culture god the best. Come dream with me. Dream of a fight for something bigger, something more important and worthwhile. We need to fight for justice and peace, for the walls between us to come crashing down. ”
