What are these implications you're talking about?
If something can be known with certainty, that certainty is an inevitable truth. To be sure of something is to acknowledge that nothing else can happen instead. If something else couldn't happen, god couldn't be sure.
An omnipotent god would know with complete certainty what you are going to do in your life. This knowledge isn't in any way go to affect your actions.
Stating your premise over and over doesn't make your conclusion anymore valid.
If he knows with complete certainty what you will do, than that means you can not choose to do anything but what he says you will, which means that you have no free will.
He isn't telling you to do anything, he's merely observing your actions. If he told you what to do in the first place, you wouldn't have free will whether he knew what you were going to do or not.
The mere knowing what you do means you can't do anything else.
If I knew with absolute certainty that at a certain time and date you were do eat cornflakes, that would mean when that time comes around you would have to be eating the cornflakes.
If you were to do otherwise, that means I was wrong. But I can't be wrong because I had absolute certainty, which means that you couldn't possibly do otherwise.
Which means you did not have free-will in the matter.
