Ah
@Jos. I just thought about this one.
If you say that people live fulfilled happy lives, then that means you must agree that people are free, but all of them are dependent.
So to be truly happy, one must reach the level that is considered true happiness. Do you agree?
Likewise, to be truly free, there must be a level, one must reach, which is considered true freedom.
So it means there is a standard, or determining factor involved in what is true. Agreed?
Therefore, once that standard is reached, a lesser being cannot deny that a person is not truly free, truly happy, etc., because that standard is not set by them.
It's like a measuring tape.
A person may use a measuring rod to measure someone's height, and say they got an accurate measurement... but is it?
To the standard set by those who determine the rule, but that standard may not be in agreement with the truth.
Nonetheless, we accept it, because it is the only started we know, with our limited understanding.
The same is true with happiness, fulfillment, freedom... We set our own standards.
The creator likewise has his own standards, and they are vastly higher than ours.
Moreover, they are absolute - the highest standard possible - they are true.
So we can't contend with them. Whether we agree with them, or not, truth is truth, and they are set, so no one can change them.
So one can be truly happy, truly free.. if they reach the standard of true happiness, and freedom.
Makes sense?
