Christians are now the light of the world (Phil 2.15) because they are in Christ who is The Light of the world (Jn 8.12). The Christ who is within all Christians by the Holy Spirit's presence ensures that Christians everywhere shine as light in the world.
They shine not only in 'churches' on Sunday but in every area of life where legitimate human endeavour takes place all through the week. They do that in marriages, families, 'para-church' organisations, neighbourhood groups, art groups, businesses, scientific research, professions and trades of every kind, farming, recreation, entertainment, and in all other activities 'too numerous to mention'.
Implications
The main point is that the LDc should do its job to prepare all the saints for the work of ministry (Eph 4.11) out in the world in all the various areas that I have listed above and more. Correlatively, the LDc should not try to be a political group, or run a business, or imagine it is a family, or indulge in too much entertainment. It's main focus is Word and Sacrament so that the saints are empowered for ministry (service) in all non-church areas during the week.This thought is implicitly in the people's words after Communion in the Anglican** church's liturgy:
'Father, we offer ourselves to you
as a living sacrifice
through Jesus Christ our Lord.
Send us out in the power of your Spirit
to live and work to your praise and glory. Amen. (emphasis mine)'
Second, it should restrain itself from grabbing all the saints' time so that they have the opportunity to pursue the Lord's business outside the confines of the church's ambit. Some churches even boast how they have a meeting every day or evening! No wonder the Body has so little impact on societies in which they live!
Perhaps some church ministers should work part-time in the church and part-time outside so that they remember what the church is actually there for.
Third, the congregational-structure ought to consider itself as an institution alongside other Christian associations working in the same vineyard. Being so, it should not suck up all the best talent found in the wider Christian community on the basis that 'the Lord should have the best available'! Of course, the Lord should but this comment is under-girded by a division of the world into sacred and secular. It understands the church to be in the sacred realm and therefore to be the realm along with missions deserving of the best.
However, any realm can be sanctified by the presence of God's people unless certain civil societies make that impossible. In some societies the possibility also exists to develop separate structures*** to form Christian schools, or Christian home-schooling, universities, political groups, labour organisations, and etc.
I tend to favour the formation of separate associations in some cases (particularly in schooling). Such associations force our present society to reckon with the fact that Christian witness in the wider sense is public and not just private.
*I do realise that my title's aspiration will have varied applications for Christians depending on the country and political system they live within.
**The pity is one doesn't hear this emphasised in the Anglican Church.
***The Netherlands, at the beginning of the 20thC is an outstanding example of where this societal development took place. Unfortunately it didn't save this society from a severe deviation from the Word of God with respect to same-sex 'marriage' and other matters. However, I don't believe that its societal structure as such led to that deformation.
