We've been talking a lot, both in class on Sunday, at Trek on Wednesday, and elsewhere, about the elevation of God's name and how much emphasis he puts on us using it rightly and with reverence.
For reference sake, here is an article I wrote a little while ago as a Gospel tract for unbelievers, please take a moment to read through it in order to hone your personal language and discernment of the holiness of the name of God.
God Will Not Hold Him Guiltless That Takes His Name in Vain, by Canyon Shearer
Many of the names that are blasphemy because they are used wrongly are not inherintely blasphemous. Such as refering to Jesus Christ as Goodness and Gracious is not blasphemous at all, if used reverently. An example of this that I like is Jars of Clay in their song, Oh my God
And Daniel 9:19, "O Lord, hear; O Lord, forgive. O Lord, pay attention and act. Delay not, for your own sake, O my God, because your city and your people are called by your name."
