The most critical times in life are those between seasons. When you are embracing a new thing, but not fully finished with the old thing. It is in the transition, that your focus can be lost.
Consider the function of a great machine. Though it is powerful and efficient, it can be limited by a simple latch, bolt or coupling. A minor part can impede major progress and a simple repair inhibits a complex production.
This is the same when you apply an old mindset to a new environment. What served you in the past must remain there, what was once harmonious, has to be retuned for your new assignment and focus.
Your new undertaking will have the same tools, the same colleagues and the same workplace. What will be different is your thinking, your perspectives and your accountability. Can you see an old thing, with a fresh set of eyes?
Luke 5:38
But new wine must be put into fresh wineskins. And no one after drinking old wine desires new wine but says, ‘The old is good.’
