Thank you, that was quite helpful.
There are times when although I understand an issue enough to believe it. However, sometimes when I am asked to explain it, I can not come up with an explanation that makes logical sense to the person I am trying to explain it to.
In this case, my wife seems to believe and except the concept of predestination, but doesn't understand how that would include things like the colour of the socks we choose. She might not have a problem for a specific purpose in mind in order to bring a plan of God's to fruition. However, she does not see how those things are important to God all the time.
The way I see it however, is how do we know God doesn't have a purpose in mind in is choosing the colour of the socks we wear on a given day?
This of course might be argued against by saying something like: How in the world would sometime as trivial as us choosing the colour of our socks, alter God's plan?

You said my question is easy to answer and I think you gave a good answer, but I must admit I find it hard to wrap my mind around the whole thing.
By the way, I was also told Spurgeon spoke on this issue and it was somewhere along the same lines as RC Sproul's answer.
I think I am going to try to find it.
