What would you say is the opposite of time?

Start with perspective, the physical world uses time to discern processes and their effects. So the opposite would remove processes and their effects and take a linear plotting of events and change the perspective from that line to a dot with everything stacked on that dot happening all at once. Which is how Padre Pio described how God sees things. So if you prayed for an already deceased love one to experience an easy death, God would understand and ease the suffering of that loved one while in our timeline they had already died.
