In our modern world, there are few regions or ethnic groups which have received absolutely no gospel message, when considering these regions and groups in their collective entirety. Without any doubt, however, per capita evangelization varies greatly from one area to another. In the United States, for example, one would be very hard-pressed to find even one person who has not at least heard the name of Jesus. In some of the more remote regions of the earth, the percentages of those who have heard of Christ drop down into the single digits.
But regardless of the quantity of Christians among any given demographic group or in any given region, one truth holds true. In God's eyes, EVERY PERSON IS A NEW FRONTIER. Every unreached human being on planet earth is a mission field, a virgin territory.
Never feel that your part is insignificant, no matter how small is may seem in your estimation. Great things start small. Every soul matters. Dare to be one of God's fearless trail-blazers, cutting new paths into the hearts and lives of those who have never heard how much they are loved by God.
