What’s in a Name?

Perhaps there is a story in the name and lives of the sons of Adam and Eve:

Cain means acquired
Abel means a breath; vanity
Seth means appointed

“By the work of my hands, I attempt to acquire a name for myself. But this, too, is vanity, a grasping for the wind.
But God appoints another way. God’s way.

The Name of God

Now the man had relations with his wife Eve, and she conceived and gave birth to Cain, and she said, “I have obtained a male child with the help of the Lord.”
Genesis 4:1 (NASB)

Eve is the first to refer to God by the Name.

On the one hand, this points to intimacy. God is not merely “out there” to her, but close enough to call by name. God’s very own name.

On the other hand, is she using the Name in vain? Is Cain’s identity wrapped up in this vanity?
