Well, what would you do if you were a follower of Jesus? Would you pay homage so you can buy food? Would you pay homage so you could sell product to provide for your family?
The Christians did not, and many of them suffered because of it. They had to go outside the city to sell product, to buy product. However, the people bought & sold at the city gates, not outside the city.
This reminds me of sports, and other activities today. We don't see idols- things that sit on shelves or pedestals. We see things like, "I can't go to church if I want to play on a team". Where people give up, compromise their walk with Christ for the sake of being able to play sports and have friends on the sports teams. This is, in many ways, more difficult because there is no law that teaches that you have to be at all church events or church gatherings. Furthermore, enemies of the Word like George Barna, who are influential in Christian circles are teaching that being involved in the body of Christ is optional. "Personal relationship with Jesus" is taught, and taught that obeying Acts, Hebrews, and 1 John where we need to be gathering with the believers in an INCREASING manner, is optional.
Maybe Christians need to say, "On Sunday morning I get to be with the believers, and worship together, in obedience to God", "And I will go with the Church when they do different functions, and skip my practice. Therefore, maybe I cannot play sports in this culture." People are ditching the teachings of Scripture in order to gain the things of this world- friends, prestige, and to play on a sports team. May God forgive them. May Christians today be willing to sell outside the city gates & never bow to idols. May they follow Jesus, and not bend to the pressures of this world.
