It causes us to go into a shell, just not be bothered. That's the easy way to face the differences in people. It does not reflect the power of Christ in our lives. The power of Christ empowers us to overcome any differences we may have with another person who loves Christ as we do. When Jesus prayed for our unity it was also the empowering agent to bring the oneness about.
Prayer is empowerment.
Elijah prayed for rain and it rained. Elijah prayed for it not to rain and it did not rain. Paul and Silas prayed until the chains fell from their hands and feet. Peter, James and John prayed for a lame man to walk and he got up, not just walking but also leaping and praising God. Jesus prayed for the bitter cup to be taken away from him.
