According to 2 Corinthians.....
1. The gospel is how we change

2. The gospel is what empowers me to serve
2 Corinthians 3:5 "It is not that we think we are qualified to do anything on our own. Our qualification comes from God."
3. The gospel is where I meet God
2 Corinthians 4:6 "For God, who said, “Let there be light in the darkness,” has made this light shine in our hearts so we could know the glory of God that is seen in the face of Jesus Christ."
