Given a choice, do you think God should -
a - smite people who don't believe in Him in order to make a change in the world
b - force people who do believe in Him to change their opinions, eg by appearing in front of them and shouting a lot
c - attempt to get people who believe in Him to change gradually over time
When God in the Old Testament is shown as doing a, people tend to say they don't like that God much.
When He is described as doing b, people complain about free will.
The reality is you can't have a God who is all-powerful, and insists on his own moral values, and also allows humanity to have free will to make their own choices (unless they are such puppets that their free will is totally constrained to doing what God has already decided is 'right')
If you think the God who would do c is too ineffectual for you to bother believing in, that's your choice. I believe that God exists, and I don't believe that He does a or b.
