Well then … in that spirit!
Based on nothing more than the definitions you helpfully provided under the poll itself, the synergism option looks the most reflective to me (through my own biased lenses) of what scriptural testimony showcases most often. While we can certainly affirm that all praise and glory belongs to God, through whom and by whom we are even here at all, much less rescued from our sins - we can also note that salvation isn’t a passive bestowal of some status, such as if I just pick up a rock and paint it. The parable of the potter and clay notwithstanding - we are a living and responsive clay (or we are expected to be, anyway). We are here for a function - whether it be of ‘honorable’ use or of ‘mundane’ use - but useful and active we are expected to be. So we most definitely participate in our salvation, even if we are powerless to either initiate or sustain it without God’s presence. Our lives lived are our only way that such salvation is even being worked out. It is the visible part of our salvation - visible to us and our own conscience at least; not necessarily visible to the world at all points - although we are expected to be that too, and not always be a lamp hidden under a bushel.
