Jer 29:13-14a You will seek me and find me if you search for me with all of your heart. I will be found by you 

Many of us claim that we found God, but he is not hiding from us.  We were the ones who wandered away, like a child seeing something at the toy store.  He is patiently waiting for us to return to him.  When we call out to him, he responds to us.
