1 Today if you hear his voice, do not harden your hearts, as in the provocation. From George Fox's Journal:
But we resolve to hear the Son, as both the Father and he command; and in hearing the Son, we hear the Father also, as the scripture testifies. For the letter to the Hebrews says, "God, who at sundry times and in various ways spoke in time past to the fathers by the prophets, has in these last days spoken to us by his Son:" mark that, God has spoken to us (his apostles, disciples, and church), by his Son. And where, some have objected, "That although Christ did speak both to his disciples and to the Jews in the days of his flesh, yet since his resurrection and ascension he does not speak now." The answer is: the Jews could not hear his heavenly voice then, neither can those who say they are Christians, but today are in the same nature as the Jews were then. But the disciples of Christ, who learned from him, they heard his voice then and hear it now.
After Christ had risen, Christ spoke to the Apostle Paul and to the rest of the disciples, including John, when he wrote his revelations. And the Apostle said to the Hebrews, "See that you do not refuse Him who speaks. For if they did not escape who refused Him who spoke on earth, much more will we not escape if we turn away from Him who speaks from heaven, who neglected and resisted Moses, and who died under the hand of two or three witnesses. Whoever resisted Moses' law (who spoke on earth), died for it without mercy.
That was a natural death. But they who now neglect him who speaks from heaven, they neglect their salvation. Therefore while it is still called day, do not neglect to hear his voice. Those who do neglect to hear his voice while it is called day, harden their hearts. Heb 3:15
The Apostle said that God at sundry times, and after diverse manners, spoke to our fathers by the prophets; but in these last days God has spoken to us by his Son, mark, has spoken to us by his Son. For which reason, John said in the Revelation, "He who has an ear, let him hear what the spirit says to the churches." Rev 2:7. "And Christ is said to speak from heaven." Heb12:25.
