Isaiah 51:12-13, 15

“I, I am he who comforts you; who are you that you are afraid of man who dies, of the son of man who is made like grass, and have forgotten the LORD, your Maker, who stretched out the heavens and laid the foundations of the earth, and you fear continually all the day…

 “I am the LORD your God, who stirs up the sea so that its waves roar— the LORD of hosts is his name.”

… Can’t a paraphrase go something like this:

Who are you that you are afraid of man who dies, you’re afraid that man won’t think your humble, that they will say you are not smart, that they won’t approve of your ministry skills. Wait a minute, you have forgotten all about the LORD, your Maker, you are not thinking right about Me… the One who stretched out the heavens and laid the foundations of the earth. I am your God and you are afraid of all this stupid stuff like you are?! 

I am the LORD your God!
