William Still was pastor of the same church in Scotland for 52 years. He died in 1997. He wrote a little book titled The Work of the Pastor. In it, he wrote the following:
Make sure you are called to the ministry, because the world gets worse and worse, and if ever there was a day when an evangelical minister could become a conventional member of society and fulfil a merely social role or occupy an official status, it is not today.
In which land is the church not in a real missionary situation as pilgrims and strangers in an alien, enslaved world? Even places with a rich evangelical heritage can take nothing for granted. When the superficially evangelistic community exhausts the solid biblical capital it has inherited from its forefathers, what is there to fall back upon?
There is more likelihood that it will become increasingly worldly in ostensible attempts to maintain communication with the lost world than that it will be willing to be led back to a solid biblical diet by ministers called of God to give it what it needs and not what it wants.
You need to be called of God to stick out from a complacent, alien community like a sore thumb. Nor will you need to try to stick out. Just be faithful, and God will arrange it, and you will be the talk of the community, however self-effacing you try to be.Work of the Pastor; Kindle Location 1164.
He also says this, which many American ministers who grotesquely marry a peculiar civil religion to the Word of God need to heed:
Because of the nationalisation of the church under Constantine, and the institutionalisation of it subsequently, she has failed to see that as a remnant church, gathering and building up a hidden Kingdom in an ever alien world, she is always in a missionary situation. The hope of the Christianisation of the state, or even the Christianisation of a complete community, is vain.Work of the Pastor; Kindle Location 801.
