According to Luke 16:13 (ESV):
No servant 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.
It seems to me that God gave us the desire to pursue certain things for a reason to begin with, so being successful and enjoying your career isn't necessarily a sin in and of itself. Is this the correct attitude?
How can a Christian keep God in the center of his or her life and properly enjoy worldly ambitions (such as a successful career)? Is there anything wrong with being focused on your career?
