16 ^1-2 Keep me safe, O God,
    I’ve run for dear life to you.
I say to God, “Be my Lord!”
    Without you, nothing makes sense.

³ And these God-chosen lives all around—
    what splendid friends they make!

⁴ Don’t just go shopping for a god.
    Gods are not for sale.
I swear I’ll never treat god-names
    like brand-names.

I find this passage incredibly true! We cannot live without God, God is the centre of our life but people just treat God with contempt! We all agree that we cannot live without God, but we all choose to ignore his presence. 

I really like what he mention later, don't just go shopping for a god. That is very surprising to me. Because who shops for a god right? The implication here is huge, we in effect choose our gods. Why? We can say we love God and all, but the fact is we do not! We only choose what we want and what we do not want. Lets say God tell us to go do this, but we think, nah i am not going to do it. In effect, we are putting ourselves before God and making us a god in our own image. We only choose what we like to follow. We like money and we choose money as our god. even through we may not say it out consciously , but that is what happens. We choose what we like and want to be our god and leave God out and we treat Him with contempt.
