Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you. 2 Corinthians 6:17.
As God's commandment-keeping people, we must leave the cities. As did Enoch, we must work in the cities but not dwell in them.
The truth must be spoken, whether men will hear, or whether men will forbear. The cities are filled with temptation. We should plan our work in such a way as to keep our young people as far as possible from this contamination.
The cities are to be worked from outposts. Said the messenger of God, “Shall not the cities be warned? Yes; not by God's people living in them, but by their visiting them, to warn them of what is coming upon the earth.”
When iniquity abounds in a nation, there is always to be heard some voice giving warning and instruction, as the voice of Lot was heard in Sodom. Yet Lot could have preserved his family from many evils had he not made his home in this wicked, polluted city. All that Lot and his family did in Sodom could have been done by them, even if they had lived in a place some distance away from the city. Enoch walked with God, and yet he did not live in the midst of any city polluted with every kind of violence and wickedness, as did Lot in Sodom.
He [Enoch] did not make his abode with the wicked.... He placed himself and his family where the atmosphere would be as pure as possible. Then at times he went forth to the inhabitants of the world with his God-given message.... After proclaiming his message, he always took back with him to his place of retirement some who had received the warning.
