When reminding the disciples of Jesus in Corinth that they were neither wise nor powerful nor of noble birth, St. Paul is not simply reinforcing the humility to which all the followers of Jesus are called, but reminding them that God can and will do great things through all of us despite our backgrounds, lack of education or wealth.
How wonderful! God takes the ordinary in each of us and shapes if into something transformational for others. We have only to allow God to work in and through us as we are. God knows the gifts we have and they are not measured by human standards. In fact, what we might consider a weakness, God might call a strength.
The history of the bible and the church is replete with believers through whom God worked despite their weaknesses. David comes immediately to mind. So does St. Augustine who resisted God's work in and through him until God finally convinced him that it was not his learning that was important, but his humility. When Augustine finally let God teach him, he became one of the most important teachers in the history of the Christian west.
Today, let God use you as God wants.
Have you ever met anyone who seemed too weak to announce the Good News?
