How can you enter into Conversational Prayer if you don’t know who we are praying to?
Under the New Covenant not only are you standing before God you are in Christ and He is in you. When this revelation becomes real in you, you no longer see God at a distance because now you know He dwells within you.
How do you know what God's called you to do? Hearing His voice is key. Without hearing His voice you're left to flounder.
