Is it wrong to fear God?

Hare Krishn! A few days ago, I had this thought "Am I in the wrong for fearing God?" For context, I've been home alone for quite a while and my father called me to remind me to offer Milk (prasad) to Laddu Gopal's idol. I asked him whether doing that was mandatory, and he said yes. So I got up and offered milk in a copper glass. During this process, I thought to myself why am I doing this? Is it because I'm afraid of God that if I don't do this then something bad will happen or am I just doing what my father told me? It led me to think, should I even be afraid of God? What's fruitful in that? Because I don't remember any specific teachings of Sanatan that tells us to fear God. But because we've been so ingrained with all the god-fearing propaganda, I even remember one of the quotations our teacher would make us write in Class 1st and Kindergarten, "Fear God." At the moment I was too young to think too much about it but now it seems problematic to me. My ishta Narayan is placid and compassionate, I doubt he'd induce fear in the minds of his devotees. But I need a learned opinion for this, I personally feel that one should fear bad karma than fear god. For only our karma is responsible towards us.
