I agree! The "freewill" is only so free as God allows it, and only enacted when God allows it.
If this is true, then the will is not free and cannot be used at will.
However, with the help of the Spirit, man can serve God with the mind, while living in his sinful flesh, this why Paul says;
Rom 8
1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
Blessings,
Petro
