Actually, Phil, for most people of Faith, the idea of "summoning" ie "ordering" the Supreme Being to do something is sacrilegious and rather offensive. The subject is not about how you would do things as God but rather the way God is said to work. We all get that you feel God isn't fair by the statement you have made here...you think God is not kind. We won't argue your own perceptions of how you view God. We shall disagree, but won't argue the point. Please be respectful to other's belief in an omnipotent God who should not be "summoned" and understand that all faiths of Light are to be respected here.
We talk spirituality here and not religion. Good luck in your personal search.
