Ahem
1) If you believe God to be omiscient, and being all knowing of things past, present and future, one would conclude that he has no need to change his mind. His focus would not require change as it would always be working towards a purpose He has had forever.
2) Part 1 of this I find confusing, as most Christians would consider God loving of all things, not just those we perceive to be good. The reality to Christians is God has set rules (commandments in Biblical speak) that dictate what makes you 'good'. The line is not so clear cut as to describe in this post, but following the rules God sets makes you 'good'. He doesnt change the rules arbitrarily, although they will update with changes in the plan He has set (this is in case anyone decides to mention the fact that Christians dont live the Mosaic Law of sacrifice, because Christians believe the need to follow this ended with Christ' sacrifice).
3) Numbers less than zero only exist in certain circumstances.
Example - I have 3 brothers. If you have 2 or less brothers, your amount of brothers represent a less than null amount, which is concept I still attempt to work out.
When it comes to numbers think of this - x
2+1 = 0
4) I need an example

5) If you can ask the question, then you may have answered it
6) Read Principia Mathematica... its painful
7) Truth is relative in each personal situation. Absolute truth is a different matter. To which are you referring?
8) The integer value of 2 in addition to an integer value of 2. Basic algebra says an integer value of 4.
I have no questions.
