Does it matter if you take the Lord's name in Vain?

Matthew 12:34-40 New King James Version (NKJV)

How can you, being evil, speak good things? For out of the abundance of the heart the mouth speaks. A good man out of the good treasure of his heart brings forth good things, and an evil man out of the evil treasure brings forth evil things.

Exodus 20:7 New King James Version

^7 (A)“You shall not take the name of the Lord your God in vain, for the Lord ^(B)will not hold him guiltless who takes His name in vain.
