For My house shall be called a house of prayer for all nations. (Isaiah 56:7, NKJV)
Christ’s message, from its inception, was destined for everyone everywhere. Early on the gospel went worldwide, because it is universally applicable. Doubtless, this concept challenged the disciples’ thinking. Their initial reaction, for instance, to Christ’s conversing with the Samaritan woman illustrates this challenge. They thought that Jesus as the Messiah was merely the fulfillment of Jewish prophecies and hopes. Somehow they had missed or misinterpreted the prophets, especially Isaiah, whose message encompassed all peoples. Jesus, The Desire of Nations, was not to be limited to a single group. Salvation might be of the Jews, but it was for everybody. Christ’s followers would transcend national boundaries, international conflicts, language differences, and other difficulties, because He Himself had established the pattern of cross-cultural evangelism.
As Seventh-day Adventists, we especially see this call in Revelation 14:6—
Then I saw another angel flying in the midst of heaven, having the everlasting gospel to preach to those who dwell on the earth-to every nation, tribe, tongue, and people (NKJV).
