The message that Paul preached in Corinth has been passed to others. Paul tells us that the god of this world (Satan) tries to hide the message of Jesus from people. Satan is often successful at doing this. What seems strange to Paul is messed up people like him get to carry God’s message to others.
We should be amazed at the privilege we have of carrying God’s message to others. Not all of them will understand it because Satan is working hard to confuse people, but we still have the responsibility to spread God’s message despite all opposition.
