That is very sensible to point out how Jesus being crucified was God's will, though evil people did that to Jesus. It was His will, meaning God would use the crucifixion of Jesus for God's all-loving purpose.
And, possibly like this, the lady's paralysis might not have been what God wanted for her; possibly, it was caused by some sort of wrong thing, including not being careful. And yes He is powerful and all-controlling so He could have stopped it from happening. But now He is able to use her tragedy for much good.
This is what I now understand can be part of the meaning of 1 Thessalonians 5:21 >
"Test all things; hold fast what is good." (1 Thessalonians 5:21)
This, I now see, does not only mean to judge between good and evil things, and between people we can trust and ones we should not trust. But it means to test every thing for the good which God can do with us.
So, in the case of depression, we can use our pain and trouble to help us feel for others. And if we get how God changes us out of the depression, now we can minister however God has changed us, to other people.
God is almighty; He can easily handle any scary painful impossible shameful stuff in us. He can easily and breezily and beautifully make it go away, but also bring us into how He has us being and loving in Jesus.
So, whatever has failed is what does not work. I think I have seen how people even boast how they have tried. But that could be not humble, and could mean the person was trying on one's own. But it can take time for God to change our character; so I still have stuff which does not go away; but as I become more gentle and humble and quiet, now I have more natural immunity growing against cruel stuff in me.
And why would we try with our own effort? Possibly, we want to live the lives we choose; maybe we want to have control of our own lives; and so we do not really and truly give ourselves, all the way, to God. Because if we surrender and submit to God, then our own lives are over. And my depression could be about not having things and people which I want in my life. With God, we get into all-loving, not with favoritism for only certain love idols. And our motive needs to be to please God, not only to get rid of problems which get in the way of our doing what we please
