It is now clear to us that God can speak to human beings and they can keep on living. 5:25 But now, why should we die, because this intense fire will consume us! If we keep hearing the voice of the Lord our God we will die! 5:26 Who is there from the entire human race who has heard the voice of the living God speaking from the middle of the fire as we have, and has lived? 5:27 You go near so that you can hear everything the Lord our God is saying and then you can tell us whatever he says to you; then we will pay attention and do it.” 5:28 When the Lord heard you speaking to me, he said to me, “I have heard what these people have said to you – they have spoken well.
