God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;  (Hebrews 1:1-2 KJV)

In time past God would speak to man through men (prophets). Now we are told in these last days God has and does speak to us through the Word. God has given us His unchanging word. In the first chapter of the book of John, Jesus is identified as the Word (Logos). Jesus is the way God has in these last days spoken unto us by His own Son: For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.  (John 3:16 KJV).
