the valley of emotions

I used to get frustrated at the thought of my spiritual life having levels: certain seasons when things were so good, and then certain seasons when things were 'cold' (like I had gone down or back a level). It felt like it was possible that levels existed, but it messed with my theology.
Especially when I took into account that those seasons that seemed like I was closest to God, were not consistently when things were going well. In fact, in most recent years, I have deeply experienced the intimacy of God when my heart is broken, and I cannot see my way clearly.
I asked God to teach me about this, and He was faithful (of course) and gave me a little picture that I wanted to share with you (if anyone reads this at all).
The biggest issue was God showing me how easily I am swayed by my emotions. I would have a 'good' day, really focused on the Lord, His purposes and then something would set me off and I would get discouraged and begin to doubt that he even knew I existed.
Then God reminded me that I need to train my mind. There is not a presto-chang-o moment that will end my life as a 'moody' Christian, and begin my life as a saint with unfaltering faith. Instead, I can train my mind to no longer pursue sinful coping mechanisms. To use self-control in the area of emotions.
The picture I got was of me standing in a field, on a firm foundation. The Truth is, that I am always there on that firm foundation. Not by works, but by Grace. God's salvation work in me is complete. I am justified, and so there I stand, in the field, on a solid rock.
But as I stand there, a mist comes in and covers my eyes from seeing my firm foundation. Sometimes it's a mist, sometimes it's a thick cloud.
My untrained mind assumes I have faltered from my 'level' of faith and taken steps backward. But my renewed mind now sees the trick and I take the appropriate action: I remember that I have been firmly planted on one solid foundation for all time. I need to make a choice to seek the Truth that disperses the clouds and mist before my eyes.
All of a sudden I am Peter on the tumultuous waves and Jesus is saying "stop looking at the waves, look at me. Truth is not in the waves--they will only drag you down. It may seem impossible, but look at me: I am above the waves."
Circumstance does not dictate or change my intimate connection with the Truth of God and His love for me and His love in me.
It's a question of faith, and then faith in action.
As a female, the battle against emotions is a BIG one. But lately, it's as though I am living out miracles when I see God free me from the bondage and the idolatry of my emotions when I remember where I stand.
