The rationale for this worldwide promotion of God’s glory and salvation is clearly stated in [Ps. 96:4]: “For great is the LORD and most worthy of praise; he is to be Feared above all gods-” The fundamental reason for spreading the news of God is that he is only one worthy of praise, the only God deserving of allegiance among all people.
We promote God’s glory to the ends of the earth not principally because of any human need hut fundamentally because of God’s/Christ’s unique worthiness as the Lord of heaven and earth. Promoting the gospel to the world is more than a rescue mission (though it is certainly that as well); it is a reality mission. It is our plea to all to acknowledge that they belong to one Lord.
