Ah! I have the book. It is in the 'Puritan Paperback' selection from
Banner of Truth.
I must confess that it is a long time since I read it; you have encouraged me to do so again.
But read what Watson says at the very start of your link, which is actually the beginning of Chapter 3.
'I shall next show what gospel repentance is. Repentance is a grace of God's Spirit, whereby a sinner is inwardly humbled and outwardly reformed.'
Repentance is a grace of the Holy Spirit, and by it, sinners do not inwardly humble and outwardly reform themselves; they are humbled and reformed. The verbs are Passive. That is not to say that there is nothing for a man to do. 'Let go and let God' is a wretched doctrine. No, we do these things, but it is the Holy Spirit who impels us to do so, and therefore Watson rightly ascribes the work to Him. What does Paul say?
'.....Work out your own salvation with fear and trembling, for it is God who works in you to will and to do of His good pleasure' (Philippians 2:12-13).
I think it is
@Silverhair rather than you who is obsessed with robotics. It's not that at all. We have to believe and repent, but when we do so, it is God, by the Spirit, who has opened our heart to believe and moved us, gently but irresistibly, to repent.
BTW, in Post #27 you rather brusquely criticized
@AustinC for suggesting that there might be such a thing as fake repentance. I take it that you have read Watson's book? Chapter 2 is entitled 'Counterfeit Repentance.'
