Unreached People Groups

Missionary work can carry you to some of the most remote places on the planet.

There are some groups of people who still live in jungles in Peru for instance, where the only way to get to them is on foot or small motored vehicles like mopeds.

Taking the gospel to these groups can be very dangerous. They do not trust any outsiders and often kill strangers that frighten them when they enter their domain.

One of the most successful ways to reach these people, is to go in with a humanitarian aid group. If you can befriend medical personnel who already have a working relationship with some of these tribal groups, you may be able to safely get in to share the gospel with them.
