We live in a age with tons of distractions. Technology (Facebook - Twitter - Music - TV - Movies - Video), Peoples Opinions (Associates, News, Etc), Activities (School - Sports - Hobbies). All of these "voices" can become so loud that it can be impossible to hear God's voice above the roar. To hear God's voice will require turning down the "noise" and learning to listen to His voice first. Having "ears to hear" God's Spirit will require exercising the discipline of listening to Him first each day before the noise starts.
