Actually DS scripture is clear that God is the 1st cause of all events .He predestines the means and the method.
It is God that is the author and finisher of our faith .
Mans will is free to choose what he will, but without Gods direct intervention man will never seek God.
It is also clear that He does not predestine some for Heaven and others for Hell. The whole point of the message of Jesus Christ is that anyone can hope for Heaven, if he believes.
