Judges 12-14

Then Manoah inquired of the angel of the LORD, “What is your name, so that we may honor you when your word comes true?”

He replied, “Why do you ask my name? It is beyond understanding.” Then Manoah took a young goat, together with the grain offering, and sacrificed it on a rock to the LORD. And the LORD did an amazing thing while Manoah and his wife watched: As the flame blazed up from the altar toward heaven, the angel of the LORD ascended in the flame. Seeing this, Manoah and his wife fell with their faces to the ground. When the angel of the LORD did not show himself again to Manoah and his wife, Manoah realized that it was the angel of the LORD. (Judges 13:17-21)

Manoah and his wife speak with a messenger from the LORD without realizing it at first. The messenger foretells that Manoah's once-barren wife will become pregnant and instructs the couple to raise the baby as a Nazirite. (See Numbers, chapter 6, for laws governing the vow of the Nazirite.) The couple's request to know the messenger's name reminds me of Jacob's request when he wrestled with a divine messenger (See Genesis 32:24-30) and of Moses' request when he resisted the LORD's call (See Exodus 3:13-14). The angel of the LORD declares the name "beyond understanding" or "wonderful." 

As Manoah and his wife ponder the angel's reply the LORD did an amazing thing, in other words, something beyond understanding, something wonderful: The messenger ascends to heaven in the flame blazing up from the sacrificial altar they had built. 

So God is impossibly named, unfathomably discerned, and amazingly active. O Great Mystery! How often have I become entangled in attempting to name the One who amazes me with wonderful deeds! Better to experience and to savor the deeds than to categorize, parse, explain, or describe them...as far as I am concerned, anyway.
