I must begin by saying that I don't recall many self-perpetuating cylces that weren't somewhow negative.
There's Eggerich's "Crazy Cycle" from Love and Respect, McClung's "Saul Cycle" from The Father Heart of God, and many more cycles of blame, depression, pride or anger, with or without cute appelatives.
Why, dear reader, is it so much harder to establish good cycles in our lives than bad?
I think it goes back to our congenital sin nature. Unknowingly, we build our entire existence on a foundation of falsehoods that we hold to be true; this only changes when Christ gives us a new life.
Let me illustrate. A wise friend of mine, Karen, likes to use this:
Make a fist. From the time you are born, you are "building" this fist foundation: your original concept of truth and reality. Your home, parents, friends and school all contribute to what you believe about everything from religion to relationships. What it means to be a sibling. What it means to have goals. Everything.
Now, fold your other hand over your fist. This represents the actual, true truths you accept when you are saved and growing strong in Christ. Theoretically, they accumulate and bring us much joy!
Finally, shake your hands in a earthquake-y way so your second hand falls away from your fist. When you're shaken by difficult times, the true truths of Christ fall away to reveal the underlying, self-created truths from the past. They may be sinful, or they may not. They may simply be wrong. Either way, you can't just cover them back over with your "truth" hand; they'll still be there every time the earthquake comes.
We have to call out to God to root them out completely; not only that, to replace them with true truths! It's painful. It's wonderful. And we can't do it ourselves. I know!
There's a reason this blog is titled what it is. The old stuff in me has to go away, burn away. If I want the things of Christ, I want them for good, and I know He's working that now.
So much in my life is burning away. I want to be focused and thankful in the midst of it; only by the grace of God am I able!
God, help me to live like I know this for true.
