During the Biblical time of Moses, God used a burning bush to get his attention, however being in flames it was not being consumed, then he drew nearer in amazement. Having his attention God spoke to him from within the flames.
More than likely we will not have a burning bush experience, but has God tried to get our attention in other forms so He could speak to us? Could it have been through a tragic event or maybe another person sent to provide an answer to an unexplained vision or thought? God may use our quiet time of prayer and meditation, seeking Him and allowing the Holy Spirit with His gentle soft voice to reveal more to us.
