Notice that God will use somebody that’s messed up to tell you what’s wrong with you, sometime. God uses broken vessels to tell you about your brokenness. But sometimes, however, we have the nerve to complain about the broken vessels that deliver the message; but, can’t even identify the brokenness that is inside: "He can’t tell me nothing! She can’t tell me nothing!"
God is brilliant in His selection of messenger. He understands that it takes one to know one. He understands that sometimes the only person that can get to the drug addict is someone who used to be addicted, so He sends somebody in front of us with all of their issues just so you can see what yours are.
