Scatter or Gather

"Therefore, when he demands that we follow him, he means that we join him in that task of gathering: 'Whoever does not gather with me scatters' (Luke 11:23). There are no neutral followers; we either scatter or gather. Following Jesus means continuing the work he came to do--gathering a people in allegiance to him for the glory of his Father." - John Piper, What Jesus Demands from the World, p 70

Ouch. Do I really gather? Does my complacency in sharing Christ really mean I'm a scatterer? That's what Jesus' words say, so I guess I know the answer. Oh Lord change me! Turn my heart and disposition to serve you by gathering people!
