"If you love the glory of God, you cannot be indifferent to missions. This is the ultimate reason Jesus Christ came into the world. Roman 15:8-9 says, 'Christ became a servant to the circumcised... in order that the Gentiles might glorify God for his mercy.' Christ came to get glory for his Father among the nations. If you love what Jesus came to accomplish, you love missions."
-John Piper, Let the Nations Be Glad
Malachi 1:11 My name will be great among the nations, from the rising to the setting of the sun. In every place incense and pure offerings will be brought to my name, because my name will be great among the nations," says the LORD Almighty.
