I welcome all replies, including yours. That's almost like asking what's the point in breathing all the time. When you stop, the connection to life is lost. We may not physically see this as being the same but think about it for a second. When you ask a human a question, or engage them in conversation, even if you don't like or disagree with the answers, there's a two-way dialogue going on.
Prayer is that dialogue.
And yes, sometimes you're gonna get an answer that you'd rather not hear. The point of prayer is to point you in the direction of HIS will. I have asked the same question. Our prayers allow us to speak to Christ. It is a way of communicating to the Lord in whom we cannot see.
