’You’ don’t know what personal communication with God is like...?
I certainly do not. Nor do I know anyone who makes the claim. Not even the most devout among my dearest family members have ever made the claim that they have heard God speak to them. They all pray multiple times/day. But "communication" is inherently bidirectional.
Prayer is personal communication with God. Prayer is personal interaction with God. Communication and interaction are important in any relationship. And God can express Himself to us by any means He chooses...through nature, a sermon, experiences, even through other people. And guidance from the Holy Spirit is communication from God.
