Your question was whether people doing things God dislikes breaks God's omniscience. The word you meant to use was omnipotence. Foreknowledge of an action is not causation.
God is omniscience but not classically omnipotent. There are some things God cannot do--like act contrary to His nature. His nature is making right and good choices. God chose to give people free will. God could NOT force you to Hell or Heaven against your will because He chose rightly to give YOU the POWER to choose. Since God has given you power, He in this case in not all-powerful.
He knows in advance whether you will choose Heaven or Hell (omniscience).
He allows you in advance to make the choice for yourself (lessened omnipotence).
Understand that omnipotence isn't a biblical term but a philosophical one. The Bible does say nothing is to difficult for God (which here includes sharing power).
No, my statements had nothing to do with people, but with the cksim that an omniscient god should be aware, via the claimed omniscience, all future events.
Right the kjv is wrong then.. Face enough, you best tell all those Christians who set store by the king James that revelation 19:6 needs rewriting.
So you are aosi saying that an omniscient designer god is incapable of creating a design to christian specification?
