Who lends money to the poor without interest; who does not accept a bribe against the innocent. Whoever does these things will never be shaken. (Psalm 15, 5 NIV)
There is nothing evil about money as long as you don't do anything evil with money. That is what this verse from the Psalms says. By the way this is the only one where the word “money” is being mentioned. Money simply is useful for payment. In former times people often used to change things. Suppose somebody bought a piece of land and paid 100 cows for it. But what are you doing with 100 cows if you are not a peasant? When I receive a certain amount of money for my piece of land then this is much easier to handle. Thousands of years ago people have already realised this. In the Roman empire money had been used in many countries around the Mediterranean Sea. Even some centuries before people in Greece already used money.
But still the question is up: What has money got to do with the Advent Season? Instead of the word “money” should we perhaps rather say “richness” or “wealth”? Do we then get closer to the answer? So what has wealth got to do with the Advent Season?
