Holy Spirit vs Own option

When we are making decisions in church group, rather charismatic people will say things like > I *feel* we should... which they sometimes connect to be input of holy guidance like the holy spirit. Because I'm not convinced most times that my thought is that of GOD's input, I'll say `I think...` instead because I consider it very dangerous how some people act as if God had to tell them what to do. *The move for an own option to become a godly input seems to be quite fluent with some people. But just because we have the Holy Spirit living in us, does not mean most of our options are direct input by god, does it?* I mention this, because they will see themselves to be guided by God in the simplest of things like how do move banks in the church.... Would God not leave such duties to ourselves? Edit: **How can we determine the difference between the leading of the Holy spirit and our own opinions?**
