If one were to accept that God has a plan and that His will is to be honored, isn't hoping to sway God's plan for the future disrespectful?
-- Update --
A lot of these answers are across the board, so here's an example to help refine the question:
Someone's wife is gravely ill and in the hospital, and her church's parishioners say they will "keep her in their prayers".
It's safe to assume that they will pray for God to reverse his direction regarding her health and make her better, and it's also fair to say they're not asking him to show them the way to do it themselves.
Just making a request for him to rethink the matter, it seems. Where does that fall?
