Then you must declare God's INACTION to be an ACTION. Now, SOMETIMES, a failure to act really is an act. However, to assign blame, as you do on our behalf, you must assert a duty, which you cannot.
No, FK, I said "If God pre-ordained everything, then there is nothing you do or don't do without God's will acting on you." It's not blaming God. It's simply establishing whose doing all this is.
If there is no blame then there is no guilt and if there is no injustice then there is no justice either.
The idea of activity or idleness of God is also somewhat of an anthropomorphism. If God created everything and all outside of time, then what is He doing in time? If everything will happen according to His will, then why does He need to intervene? Is there a danger that His "plan" will not work, or that someone can railroad it? I don't think so.
Does it require divine intervention and guidance gven that everything has been preordained? I don't think so. One might really wonder what is God doing outside of time! After all, His work is done, isn't it? Or is it incomplete, which is to say imperfect?
