This clashes with long-established Presbyterian doctrine. God loves and desires to save the world. Some people are damned.
Faith is necessary for salvation.
What God chooses is what happens. Yet when we defend two or three of these doctrines, the remainder are difficult to affirm. If we propose that God loves and desires to save the world, but some are damned because they do not have the necessary faith, then God's will is not accomplished. If, instead, we begin with God's sovereignty and say God decides who is saved and who is damned and gives the necessary faith to those who are saved, it is hard to claim God loves the whole world. People sometimes just believe the way that feels most comfortable.
