I don't know mark, this sounds like a mind over matter idea to me. And that didn't work for me for years. The only way I became any better - humbler, gentler, more forgiving, (which IS control over our flesh) was to give up trying and trust God to do what He promised.
We're saying the same thing.
But here it is in Scripture:
2 Corinthians 3
3 For though we walk in the flesh, we do not war after the flesh:
4 (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;)
5
Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;
6 And having in a readiness to revenge all disobedience, when your obedience is fulfilled.
Romans 6
5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
6 Knowing this, that our old man is crucified with him,
that the body of sin might be destroyed, that henceforth we should not serve sin.
7 For he that is dead is freed from sin.
Soma = body - body of sin; be destroyed = nullified, rendered powerless;
The body of sin has no power over us. Having died in Christ we are freed from sin. The life we now live we live unto God, having died to sin. Freed from sin.
Now we can examine every thought that comes into our heads and compare it to the Bible, and reject any that don't conform. Although the longer one does this, the better one gets at early recognition, and better at believing this is true.
It is by faith in Jesus that we enter into the grace in which we stand.
By believing what Jesus did is enough that we enter into the grace in which we stand.
By believing what Jesus did is enought that we receive the benefit of His gift in causing us to remain standing even when the flesh/world/devil tries to knock us down.
In believing this is true, that we can reject every evil thing, it is true in our lives.
If we do not believe, we do not do. If we believe, we do. And in doing, God does what He promised. And we live with His nature.
Much love!
