How?

The Bible is so clear on the importance of taking every thought captive; thinking on the right things; being transformed in our minds; etc... How do I do it with lasting change? I feel like lately I'm totally having a full blown war inside between flesh and spirit... I know what's right, the Holy Spirit convicts me and leads me... but honestly over the last several weeks I've been warring inside to do what I know is right versus what I want to do. For the most part I've always found it pretty easy to do what God says, because I love to please Him, I love Him! So why now is it that I want to run away and hide from all the "pressure" that goes on when we say yes to Jesus? Why after 7 years does this craziness go on inside of me? I know deep down I want all He wants for me, I know I don't want to walk away from Him... but why now so much confusion? I'm in the Word everyday more than once... I pray constantly... I'm involved in Church... I have great spirit filled friends... so why? So anyways... any great words of wisdom would be much appreciated...

Stained Glass Masquerade by Casting Crowns:

Is there anyone that fails
Is there anyone that falls
Am I the only one in church today feelin’ so small

Cause when I take a look around
Everybody seems so strong
I know they’ll soon discover
That I don’t belong

So I tuck it all away, like everything’s okay
If I make them all believe it, maybe I’ll believe it too
So with a painted grin, I play the part again
So everyone will see me the way that I see them

*Chorus*
Are we happy plastic people
Under shiny plastic steeples
With walls around our weakness
And smiles to hide our pain
But if the invitation’s open
To every heart that has been broken
Maybe then we close the curtain
On our stained glass masquerade

Is there anyone who’s been there
Are there any hands to raise
Am I the only one who’s traded
In the altar for a stage

The performance is convincing
And we know every line by heart
Only when no one is watching
Can we really fall apart

But would it set me free
If I dared to let you see
The truth behind the person
That you imagine me to be

Would your arms be open
Or would you walk away
Would the love of Jesus
Be enough to make you stay

Chorus x2

Well if the invitation’s open
To every heart that has been broken
Maybe then we close the curtain
On our stained glass masquerade

Is there anyone that fails
Is there anyone that falls
Am I the only one in church today feelin’ so small
