Going back a bit, Bertrand you asked me if I thought free will was just a cop out. I understand how it can seem like that, almost like saying 'oh, we don't really get suffering, we can't really reconcile it, so.... free will.' Yep. I cringe at it myself (we theists can laugh at ourselves.)
However, there's a lot more to freedom than a convenient explanation for the fact that there is evil and suffering in the world. I believe that God created us for good relationship with God and with one another, but that if we could not make choices for the good then it wouldn't really be good at all. It would just be there. Be it. There would be a world without extremes, without the heights of experience as much as the lows, we would be beings of unthinking obedience with no personal autonomy or choice. To create such beings does not appear to me to be the action of a loving creator.
As for cosmological arguments and Jassy's point, I can see what you mean about the argument that if theists say the world must have a cause then so must God. But one position is to say that the universe must have a causal agent because it has a beginning - because it is expanding, and it cannot expand backwards into infinity (as I understand it anyway, I never was much use at physics though do find it fascinating)
God, however, theists would say, does not have a beginning and therefore does not need a causal agent. God is infinite, outside time, with no beginning and end. So one argument does not apply to the other.
However, I am aware of arguments against this argument as well, and continue to read them to educate myself. I wish I had a more scientific bent - luckily my dc have and are heading that way :) I'm too arty farty.
However, cosmological arguments aside, convincing or not, my lived experience is of a loving God. But I do know they are only words, and not enough. But it is what it is.
