No one can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money.
What does it mean, and what does it look like, to serve money? I wondered that myself so I looked up the Greek word that is translated serve and I saw words like slave and bondage - that last word caught my attention. I know what it is like to be in bondage to money.. to evaluate every decision from a fiscal perspective.. to care more about the welfare of the bottom line than the well being of employees. Most companies are in bondage to money and their managers are rewarded accordingly.
I am not saying that we should not be wise in how we use money - how we use money is often representative of how we serve God. I am saying that God will never be a real priority in our lives when we are in bondage to something else. Consider how the Apostle Paul told us that the love of money is the root of all kinds of evil. In a sense love is the issue. When we serve and love money we make an idol of it - and idolatry is the heart of the issue.
Open my eyes Lord to ways that I idolize money and the things that money buys.
