They give us opportunity to join the angelic choir in praising him in collective song and prayer. They help us seek guidance from his Word regarding how we serve him in the coming week. Likewise, our weekly small group meetings give us opportunity to reflect on the Word of God and share with one another the work God is doing in our lives, so that we might encourage one another, and pray for one another that our service might be all the more effective. We all serve him. We cannot pay someone else to do our Christian service for us.
Pastors are to lead, to teach, to equip members for service.
But each of us must do our own duty, as we have been called and gifted by the Holy Spirit. All Christians follow Christ in denying the self and in serving others. The Lord served others, and service is not beneath the dignity of anyone who accepts Jesus' death as being payment for his or her sins. He served us, and calls on us to serve others, to do good to all. Whether we want to or not, we represent Jesus Christ in the office, on the highway, in our homes.
