Did John Bunyan believe in predestination and irresistible grace?

This particular question is concerned with John Bunyan's stance, rather than the stance of Pilgrim's Progress, which is addressed in a [related question](https://christianity.stackexchange.com/questions/12383/does-bunyans-pilgrims-progress-state-a-position-on-predestination) . I learned of Pilgrim's Progress through reading works of reformed theologians (many of who highly recommended Pilgrim's Progress), and thus I assumed that Pilgrim's Progress also believed in predestination. I'm no longer sure of that, and I'm not even sure if John Bunyan himself believed in predestination. (Wikipedia doesn't seem to say either way) Thus, the question: did John Bunyan take a stance on predestination and irresistible grace?
