I was reminded of one of many books I have found helpful by A.W. Tozer entitled: "Jesus, Our Man in Glory". The book is a compilation of Tozer Sermons on the first half of the book of Hebrews.
"In the past God spoke to our ancestors through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom also he made the universe. The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven". (Hebrews 1:1-3 NIV)
God's final word is His Son, Jesus, Our Man in Glory... and He is still speaking today!
