“No one is like you, O Lord; you are great, and your name is mighty in power.”
The word “name” here is from the Hebrew word for “renown” ~ shem. This same word is sometimes translated fame. Sometimes we say someone “has made a name for himself” to indicate s/he has become successful and possibly even powerful.
The Lord is known to this prophet (Jeremiah) as being more mighty and powerful than any being in existence.
Do you see the Lord this way? Not in a general sense, but a personal sense? Think back over your life. In what way has the Lord used his power to cause certain “coincidental” things to occur in your life just at the right time?
