 Growing in your ability to hear the Holy Spirit is as simple as knowing the Word, obeying the Word, and removing the distractions of this world. Since you are already a Spirit-filled believer, you can already hear the Holy Spirit. Just as you were born with natural senses of hearing and seeing, so you were born again with spiritual sight and spiritual hearing. Hearing the Holy Spirit isn't a skill to be learned, but a sense to be sharpened. You already have this ability. You can already hear the Holy Spirit. So know the Word and you will better discern God's voice and nature.
