Dozens of times Scripture says that God does things “for his name’s sake.” But if you ask what is really moving the heart of God in that statement (and many like it), the answer is that God delights in having his name known.
The first and most important prayer that can be prayed is, “Hallowed be thy name.” This is a request to God that he would work to cause people to hallow his name.
God loves to have more and more people “hallow” his name, and so his Son teaches Christians to put their prayers in line with this great passion of the Father.
“Lord, cause more and more people to hallow your name,” that is, esteem, admire, respect, cherish, honor, and praise his name. It is basically a missionary prayer.
