God not only wants to save us, but use us for His glory.  We are a new creation, with a new purpose, and with that calling comes the power from God to do what He has for you.  What gifts has God given you?  How are you using it to build up the body of Christ?  Paul encourages this church in Corinth that we all have a part in God's plan, and every person is needed & necessary in the work of God.
