From Following Jesus by N.T. Wright:

“If the Son of Man is the King of the world, we who worship him are to follow him, and are therefore sent into the world with a great commission. We are to make disciples, learners, followers; we are to baptize them, and teach them to observe all that Jesus commanded. There is no corner of the created universe over which Jesus does not claim rightful sovereignty. We are to be his agents, his ambassadors, in bringing the word of his kingdom to all his subjects.”
