Our ecclesiology or understanding of the church has a huge implication for discipleship. If we see church as an attractional place to observe, then our disciples are going to resemble after school help in movie-theater consisting of a few greeters and concession stand workers.
On the other hand if you see the church as an extension of the living and breathing body of Jesus it makes all the difference in the world. Disciples in this context are transformed from ordinary fishermen to fishers of men. Infused with new life, hope, dreams, passions, and commitment they are compelled to live like Jesus, love like Jesus, and leave what Jesus left behind. When confronted with hunger they respond because Jesus responds. When they encounter an enemy they turn the other cheek, go the extra mile, and give away their coat. When reports of an earthquake come across the air they mount an all out relief effort. When children are abandoned they become their adopted parents. When their neighbor is alone they sit with them. When blessed they become the one who blesses in return. When given power they use this power to help those who can’t help themselves. They are in process. They are discovering a new kind of righteousness. They are alive. Boredom is far removed from their life. They are filled with His Spirit and infused with power. They are alive. They are on fire.
Jesus declares them blessed and invites them into their reward.
There’s nothings wrong with greeters and doorkeepers, especially when they are holding the door open for people as they leave the church fully alive and fully engaged as the body of Christ.
