All Christians are called and equipped to be involved in the work of the ministry for the building up of Christ's church. There is always plenty of work to be done, from evangelizing to cleaning bathrooms, and no work should be beneath us.
"Do nothing out of rivalry or conceit, but in humility consider others as more important than yourselves. Everyone should look out not only for his own interests, but also for the interests of others. Make your own attitude that of Christ Jesus."Philippians 2:3-5 HCSB
