Body

 from whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love.
Ephesians 4:16 ESV

A body without a head isn't much of a body. So too, a Christless church is pretty much a social club without much of a purpose. The purpose of the body of Christ is to do whatever He tells us.

Jesus doesn't save individuals for them to carry on individualistically. Instead, upon faith in Christ, we as individuals become part of God's body, the church. Every part should play its part.

There's no point a hand attempting to walk around. There's no point the feet attempting to serve refreshments at a church meeting. We all need to play our parts.

We need to work properly. We might want to be the heart, but there's no point hankering after that if we're the guts. We need to find out where we belong in the church and to fulfil our roles with diligence and joy.

'Our Heavenly Father, please help us to know and fulfil our roles as parts of Your body on earth. May we follow as Christ leads, for the glory of Your name, amen'
