For its own soul the church [and me too] needs to be involved in missions. We will not know God in his full majesty until we know him moving triumphantly among the nations. We will not admire and praise him as we ought until we see him gathering a company of worshipers for himself from every people group on earth—including all the Muslim and Hindu and Buddhist peoples. Nothing enlarges our vision of God’s triumphant grace like the scope of his saving work in history. (pg. 172-3)
Many Christmas celebrations, stories, gatherings, devotionals, etc. seem to focus simply on the baby in the manger, and often they don't leave the manger.
If I never leave the manger in my Christmas meditations, I miss the scope and depth of Christmas. The baby Jesus left the manger, increased in wisdom and stature, showed us true righteousness, and gave his life to ransom a people from the many peoples of the world.
For a meaningful Christmas season—and a meaningful life—it is essential to see that Christ was undertaking a global mission when he became a little baby in a manger.
