Imagine you’re planning the trip of a lifetime to Greece. You will trace Paul’s second missionary journey — the one that began with a God-inspired vision:

When Paul had seen the vision, immediately we sought to go on into Macedonia [Greece], concluding that God had called us to preach the gospel to them. (Acts 16:10) 

What took the apostle years to complete, you are going to pull off within 10 days. That means you have to make choices. There will be some sites you see and others you won’t have time for. For example, you may consider visiting either Thessaloniki or Veria, rather than both. But that’s tough, because both cities get biblical notice.
