I read the letter that Ted Haggard had read to his former church this morning. One thing that struck me was how destructive it was for him to think that he ought to have achieved victory over his besetting sins, and being so ashamed at not experiencing that victory in the measure that he thought he should that he gave up on accountability and in the darkness sin flourished. While there is a clear Biblical expectation that a believer should generally experience victory over sin, I think we must balance that with a Romans 7 understanding that we will never be beyond the reach of sin until our bodies are made new at the resurrection.
Everyone who competes in the games goes into strict training. They do it to get a crown that will not last; but we do it to get a crown that will last forever.

I pray also that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in the saints, and his incomparably great power for us who believe. That power is like the working of his mighty strength, which he exerted in Christ when he raised him from the dead and seated him at his right hand in the heavenly realms. Eph. 1:18-20
