My friends, I hope that you can enjoy the simplicity of this scripture and yet the power that it teaches. First, it asks a very important and time bound question, "today, if ye will hear his voice," or in other words, Christ is speaking to you, and not tomorrow, not later, but today; and the question is, do you hear Him?
How do we hear His voice? We hear His voice from the mouth of His prophets and apostles, we hear His voice from the pages of holy writ, and we hear His voice spoken to our hearts by the Holy Ghost and by the Light of Christ through our conscience.
