Yes, it depends ...and you may have to wear them if you can't control it. But, the number one, referred to here, is like the final answer of a top ten list.

Look out for number one!!

Again, what are we referring to??

The best ...

The top performance ...

The most significant, or of highest value ...

The one who comes first in our life ...

God is all of these, or should be ...yet, we don't have to look out for Him.

We should rather ...look into Him, to find out who He is.
