The Scriptures teach us that the we are to make God's name holy in all of our lives and actions. This is not just seeing God's name as holy on the Lord's Day (or for two hours on the morning of the Lord's Day), but is to be a lifestyle that we live out. We are to make people see the holiness of God through the way in which we live out our Christian faith in the daily grind of life.
Hallowed be Thy name; that is, grant us, first, rightly to know Thee, and to hallow, magnify and praise Thee, in all Thy works, in which Thy power, goodness, justice, mercy and truth shine forth; and further, that we so order our whole life, our thoughts, words and deeds, that Thy name may not be blasphemed, but honored and praised on our account. -Answer 122
