The Gospels talk about two important parts of Christianity.
Christian service does involve private prayer and public worship but also what our Lord Jesus calls us to do. #dwjwd (Do What Jesus What-have Done). Jesus calls us to love God more than our own life - this is a hard task. He calls us to a life of humble service.
Holy Communion is meeting with your fellow Christians and sharing bread and wine.
John 13:1-17, 1 Cor 11:23-26 By receiving the bread and wine we are strengthened. These are symbols of Jesus' body and blood shed for us. How-ever they work for we can not know, communion does strengthen us.
We need public service so that we can make a difference outside, but our journey is to weave the two aspects of service together; private prayer and public service.
We need present day role models who do this well and the Queen is a shining example of someone who has led a life of private pratice and public worship.
Jesus is our Lord. Amen
