Those who live according to the sinful nature have their minds set on what that nature desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. (Romans 8:5)The dominant party is evidenced by our thoughts.
I was recently off-handedly told that it's ok if I work long hours at work as long as I love what I'm doing. I was not in a position to respond to this comment, but I disagree. There are many projects at work that are mental traps for me. They're enticing with challenge but the real possibility of solving them. Similar to what I wrote about yesterday, I will think about these projects any chance I get, and it tends to bear fruit as it's often this background processing where good solutions occur for me.
Now, I'm very thankful for my work, and I don't think there's anything bad about it. But it's also not the most important thing. Therefore, if work is stealing cycles from what the Spirit desires, it is a concern. What I spend my time on is a big contributor to what my mind is set on, and because of this, work should be balanced.
How about you? What's your mind set on? Do you know what it is that the Sprit desires?
