Imagine how God feels when we act the same way. We're so busy with distractions in life that most of the time we don't even recognize His voice or that He's even present in the room with us. God doesn't need our attention, but He does want our attention. Sometimes He wants to give us instruction and other times God just wants us to be in His presence so that He can love on us.
I've been guilty of being that busy, distracted, and self-absorbed child. God swooped in and got my attention through a series of life-events and people. Since that time, I have learned to recognize my Father's voice and to carefully watch for Him. I'm not always successful, but I am still learning and God is a merciful Father--Praise the Lord.
I ran across this song by Mandisa called God Speaking. It's a very powerful song about the way God captures our attention. Give it a listen and then start listening for God to speak.
