This is the exact question someone asked me while I was witnessing to them in field service one morning. I opened my mouth to give him the usual 'parrot-like' response about free-will and the sovereignty debate between God and Satan and I found that my answer didn't satisfy me- and definitely not the house-holder.
It is one of the 1000 cuts of death that caused me to fade.
I always assumed God knew EVERYTHING that had happened and was ever going to happen, I mean doesn't the bible say that 'God knows the end from the beginning?' Isa 46:10.
The main problem apologists have with this is of course that if God knew that man was going to have thousands of years of pain and grief because of sin, as a loving God, why would he let that happen- just to prove man has 'free will'?
I was thinking about this subject again recently and checked on jw.org to see what the 'current thinking' was.
The June 1st, 2006 Watchtower contains this jaw-dropping gem:
17 Jehovah apparently chose not to foresee what Adam—and Eve—would do, even though He has the ability to know everything in advance. It is therefore a question, not of whether Jehovah can foresee the future, but of whether he chooses to do so. Furthermore, we can reason that Jehovah, being a God of love, would not knowingly and cruelly predetermine that rebellion—with all its sad consequences—should take place. (Matthew 7:11; 1 John 4:8) Thus, as far as Jehovah’s exercise of foreknowledge is concerned, it is selective.
So, here we have the wts, who seemingly understand the 'mind of God', saying that God has 'selective knowledge'.
Selective knowledge implies, (to me anyway), that God DOES know what is coming but chooses to ignore it, otherwise, how can he 'select' which knowledge to notice and which to ignore?
It also treats God with great disrespect, suggesting that he is like an engineer that has set some machinery in motion yet chooses not to think about the consequences. Kind of hard to believe if you also accept that God has created the stars, put them all in their place and knows their names.
Never ceases to amaze me how far the borg will go to defend their beliefs.
