Psalms | God thinks ‘IN LOVE’ about me all the time

I know that is not great grammar, but when we unpack Psalm 139 on Sunday you will totally understand what I am trying to say there.

This has to be one of the most well known and loved Psalms ever. But how can this make sense when it looks like David wants to run away and hide from God in the middle of it?
Maybe the reality that God can totally read our minds has something to do with it. Is that totally scary, or totally reassuring? Hmmm?
