In our passage, the apostle Paul brings us back to the basics. Paul reminds believers what is core to Christianity and what is “of first importance”: passing on the message of Jesus’ death and resurrection, according to the Scriptures. Steven Covey famously coined the phrase, ‘The main thing is to keep the main thing the main thing,’ about the need for organizations to keep focused to be effective. For the Church, the main thing is Jesus and his resurrection. When the core of the Gospel becomes forgotten, displaced, or even denied, Paul says we are in danger of having “believed in vain.” This week we look at being devoted to “the apostles’ teaching” (Acts 2) in being devoted to the message of the cross being the core of what it means to truly be the Church and a follower of Jesus.
