In Iran when there was no planes no cars and no buses you either had to walk or ride on a horse or donkey. If you read the book called Tales of Persia, it is about a missionary in Iran. “when the missionary was going on a journey before there was cars, planes, and buses a man stood out (a Islamic man) the man did not greet the missionary. But then the missionary said, when you go on a journey you must need bread, water, light, and a path. And then the missionary said that God is the light of the world, God also said he is the water, and he is the bread of life, and his path is eternal life.” Hopefully the Islamic man became a Believer. This example is great for ministering to people.
