The video you'll see is a professor of New Testament following the Second Missionary Journey of Paul (Paul and Silas).

Why Greece? 

See Acts 16:9-12 where Paul receives a vision to travel to Macedonia modern day Greece.

Why Travel? 

3 reasons

#1 the Bible comes alive before your eyes it is a profound spiritual experience. 

#2 Group travel with people of faith is bonding and encouraging, creates true community. 

#3 Leaving home to experience other countries, different cultures, languages, landscapes, buildings and people helps you to understand that the world is smaller than you think, our differences (that often get so magnified in our American culture) are not as great as our similarities.  International travel provides a chance to change your perspective, to grow and to learn.  You learn about yourself as you learn about others.
