It's not the question in IMHO. I don't think it's God's will we do many of the things we do.
It is God’s will that all be saved and come to a knowledge of the truth. He doesn’t want any to perish.
However, I also see in Scripture that He draws us and calls us and commands us to repent, knowing that not all will.
He clearly gives us the final choice whether we say yes, to Him or not.
So it’s His will for all to be saved, but it’s also His will for us to make the response. So is God’s will being thwarted?
There's an understatement if I ever heard one.
Genesis 50:20 (NASB)
“As for you, you meant evil against me, [but] God meant it for good in order to bring about this present result, to preserve many people alive.”
So, was God’s will thwarted when Joseph’s brother did evil towards him?
When God allowed Satan to test Job, did God know that Job would not renounce Him? When God asked Abraham to sacrifice his son, was God unsure that Abraham would obey?
When Jesus said to Peter that he would deny Him before the rooster crowed, could Peter do anything not to deny Jesus?
So, even in these little things, compared to our salvation, God is in control. So why do we think he is not in control when it comes to our salvation?
