DR, there is no such thing as free will, as free is what aniamls do and we are not animals. will and liberty is what all people are born into and is of god aka the universe. Will is moral authority or birth and liberty is legal power or physical strength. We al make choicesl a choice among sone just choices is liberty. We all emotionally reason the consequences of thise choices which is will.
With god? it is all choice as god forces nothing upon us - nothing. we can choose 'bad' or choose 'good'. People are not good or bad; they are eppople. Their choices may have good and bad conqsequences.
By making choises and then owning the consequences of those choices we coem to defeat ego for conquer fear thus full embrace and know unconditional love.
God? You are to be loving and not ever motivated to do anthing out of fear!
The best, most just reason in the wirld? because you can and becasue you want not becasue you are afraid.
Christ taught that - love - not fear.
Once you actually live out unconditional love you are an equal creator with or to God or this universe. You are a part of it not apart from it.
BTW: I'm not Christian but of all relgions. Man corrupted the idea of will and liberty thus made it "willpower" and "freewill". That's patriarchy not Christ himself for ya!
