The basic difference is that guided evolutionists see God as coming in and 'fixing evolution's path' to have the effect he wants. Theistic Evolution believes that before the Universe, God set the rules in motion that resulted in the creation he intended. Another way to look at it is that in guided evolution, God had to course correct evolution, versus Theistic evolution, the course was correct.
Think about it this way.. God is supernatural, he lives outside the laws of the natural world, such as space/time laws. For God, the result and the beginning is the same thing. When he created the system of creation, he created it knowing the result and all its history, existing all in the same moment to God. The entire concept of 'time' as we define it, and is often the biggest challenge in the fight of creation versus evolution, is all human invention based on our observations from our small point in the universe. A day to us is different than a day to people on the space station, so why are we so hung up in defining what a 'day' is to God (not to mention, the term 'day' in the Bible is interchangeable with 'age' or 'event'..) We shouldn't face the flaw of creating God in our image by defining Him or His existence with human terms.
I'm pleasantly surprised, and suddenly feel less alone.
Perhaps they aren't true, but they seem more rational to me!! Food for thought and for bookmarking.
