1. Paul's resolution (1-2)
Paul was a highly educated scholar, but when he preached or taught the Bible, he did not show off his knowledge. He resolved to talk only about Jesus who was crucified for our sins. We don't have to know many things to be Christians; we only have to know Jesus and him crucified for our sins and for the sins of the world. If we don't know Jesus, then no amount of knowledge can save or help us.
2. Faith must rest on God's power (3-5)
When Paul first came to Corinth, he was overwhelmed by the moral corruption of the Corinthians. He did not know what to do, so he prayed a lot and preached the gospel of Jesus' death and resurrection. The Holy Spirit moved the hearts of people, and they put their trust in Jesus. Our faith must rest, not on our own knowledge, but on God who works in us with resurrection power.
Application: Lord, give me a repentant heart so that my faith may rest on your power, not on my own ideas.
One Word: Know Jesus and him crucified
