The apostles didn’t preach the gospel like Christians today
Many Christians today assume that we should tell people “God loves you” or “Jesus died for you” when we evangelize, or else it’s not the gospel. Not saying we shouldn’t, but the apostles didn’t in the book of Acts.
When preaching Jesus is not a good thing
Paul the apostle once told someone to stop pointing to the way of salvation. That incident teaches us that some people should not be talking about Jesus.
