when we talk about the voice of the heart, allot of people think that its your conscience. actually that's not really what happen. the Truth is the voice of God. His Spirit(Holy Spirit) that live in our life. it is apply only for those who believe and received Jesus Christ as his or her own Savior only. those who has not receive Christ, the voice of heart is only his or her inner being which is his or her spirit. the reason for this is for the believer, they trusted Holy Spirit with their day today's life or activities. talk with Him in prayer, or just communicate within their heart. for those who has not, they only talk to them self within their heart. I guess that's my answer for this question. hopefully others can give better one. God bless.
