Listening to discern if it is the Father speaking is important because there are many voices in the world. Sometimes the issue is not even the other voices, sometimes it is wondering, is this me, my own thoughts or is this God? 

In listening to God, follow peace. Peace in your heart. your feelings may not feel that great, but you cannot follow feelings. What you can see, what you can touch, what you can hear, smell cannot reveal God’s will to you. Our 5 senses are not evil, God gave them to us. But those senses have no comprehension of the spirit realm. However, God has given us other means to listen and hear Him. Peace. Colossians 3:15 says let the peace of God rule in your heart (rule like an umpire).
