I often say the book of Acts is not the "Acts of the Apostles" unless you throw in some sort of insult about the apostles in there. It is the "Acts of the Holy Spirit (and the rather-slow-to-get-it Apostles)." I'm thinking especially of Acts 10-11. Nicole is correct about the Gospels as well. God does want to use people. It is God's idea! But it is good for us to remember we are the ones being led and to have a sense of humor about ourselves.
It is of profound spiritual comfort to me that the 12 disciples were all randos who spent 75% of their time asking Jesus dumb questions.
