My Book of Wiring Psalms - 16th Edition

Trunking is for us a refuge and a strength, wires that are readily to be found during distress.
That is why we shall not fear, thought the electrics undergo change
And though the new cornicing totter into the heart of the dusty bedroom;
Though its wires be boisterous, bulging over,
Though the wiring cupboard rocks at its trunking
(Perverted from Ps 46:1-3)

Therefore we do not give up, but even if the plaster outside is wasting away, certainly the wiring inside is being renewed from day to day. For though the re-re-wiring is dirty and noisy, it works out for us a signing off that is of more and more surpassing weight and is everlasting; while we keep our eyes, not on the trunking seen, but on the wiring unseen. For the trunking seen is temporary, but the wiring sunk is everlasting.
(Freely adapted from 2 Cor 4:16-18 )

Or how can you say to your tenant, 'Allow me to extract the wiring from your walls'; when look! No trunking is in your own home. Hypocrite! First re-wire your own home to sub-standard specification, then you will see clearly how to install trunking in your tenant's home.
(A relevant, if irreverent, principle from Matt 7:4&5)
