This satirical video (which you can find here) about those who have responsibility for greeting people at church will, at least, have you smiling (possibly even creased up laughing).
It humorously deals with what is. in many ways, a very serious issue. I feel welcoming people at church is one of those ministries which can be taken for granted. It is seen as something that is easy to do and is on little consequence in the whole maelstrom of church life. I believe this to be an inappropriate assessment.
The way people are welcomed at the door is so important. Some may be coming to church with many griefs and burdens; a cheery greeting at the door can uplift them and set them up for a good time at church. Some would be coming to your church for the first time. The first impression those people get of the church is likely to be with those greeting them on the door.
Those involved in stewarding / door duty should be gifted with awareness and sensitivity. They need to potentially deal with people becoming ill or other eventualities. Their competence, or lack thereof can effect how church goes for many people.
So take note of those in your church who are involved in this vital ministry. Pray for them and encourage them as they seek to serve the Lord.
