Set your minds on things that are above, not on things that are on earth. For you have died, and your life is hidden with Christ in God. (Col 3:2-3)
When I stop, I generally think about work. It occupies me my day-to-day life for some 45 hours a week. It occupies my thought-life for probably more like 60. When My mind gravitates to thinking about work when I come to rest. I'm not saying this is all bad - part of it comes from the fact that, on the whole, I really enjoy my job - I really enjoy problem solving, making things quicker, more elegant, more feature-rich, occasionally less buggy (for those who don't know - I'm a software engineer, which is a fancy-sounding title for a computer programmer).
I just wonder whether I would more profitably spend my time thinking about other things. Partly, I generally find thinking about work outside of work unhelpful - generally I go over and over the same thought patterns, without getting anywhere. I reach the same conclusions, and wait until I'm physically at work before I can do anything about them, at which point I've usually forgotten what it was I was thinking about.
Matthew Henry wrote this, in comment on Colossians 3:
We must make heaven our scope and aim, seek the favour of God above, keep up our communion with the upper world by faith, and hope, and holy love, and make it our constant care and business to secure our title to and qualifications for the heavenly bliss. (Matthew Henry's Commentary)
What if instead of tending towards work and labour, my mind tended towards God and rest? What if when I am still, instead of puzzling things out, I talked to God?
There is a river, there is a road
A place of holy riches untold
It's where I'm supposed to be
Where I'm supposed to be
My Heavenly
