There are many people who believe God has created every person with freewill.
They are indoctrinated. No-one has free will.
If God has given each human being freewill then how can this God take any action without causing a reaction. (Anything that God does is going to have it's effects on whomever or whatever)
Correct.
Also, if free will existed then there would be no punishment by god for us taking any given action.
Free will means what it says. You are free to undertake any action of your will. But if any action at all is subsequently punished then it was never free. It was a false choice made with a gun to your head.
There are powerful people on this Earth who know that religion is false and there to control the masses and they know that there are NO RULES other than the laws of the universe (gravity, science etc). These people therefore kill people any time they wish. They can do anything.
The reality however is that they are still very limited in the choices they have. So it isn't really free will they have.
This is old ground.
If you are given a choice of a red ball or blue ball many would say that's a free choice. Free will. But if what you really want, what you really "will" is for a green ball then you're out of luck because that choice is not on offer. You have a limited choice. Not free will.
Life therefore is simply an extension of this system of very very limited choices. It isn't remotely free will.
In the context of Christian dogma, only god has free will. For only he can kill men, women, children, babies and as yet unborn babies with reckless abandon, at will, and get away with it Scott free. Only he can make earthquakes happen, tsunamis, hurricanes, volcanos erupt that result in millions of life forms dying and do it with freedom.
God is a dictator. A tyrant. An entity who rules by the law of :
"Do as I say, not as I do"
It beggars belief that Christians can't see it. But indoctrination and psychological abuse are very powerful weapons.
