God determined them to that which is good

All those whom God hath predestinated unto life, and those only, he is pleased, in his appointed and accepted time, effectually to call, by his Word and Spirit, out of that state of sin and death, in which they are by nature, to grace and salvation, by Jesus Christ; enlightening their minds spiritually and savingly to understand the things of God, taking away their heart of stone, and giving unto them a heart of flesh; renewing their wills, and, by his almighty power, determining them to that which is good, and effectually drawing them to Jesus Christ: yet so, as they come most freely, being made willing by his grace.

The Westminster Confession of Faith Chapter 10 section 1



This is really interesting because those whom God predestined unto life at the appointed time they were effectually called by the word and Spirit enlightening their minds taking away their heart of stone and giving a heart of flesh by his almighty power, in which they were determined to that which is good.
Today we have many who profess Calvinism and yet still hold to a theory of free will. But not the WCF. It says that God determined them to that which is good.
