2 Peter 1:21 teaches, “For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.”
Even though God did speak directly to Abraham, Moses, John and others, since the Bible was completed God, has only been speaking to man through the Bible, God’s holy and infallible Word.
Hebrews 1:1-2 declares, “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.”
It behooves us to mention that not only is God speaking to each member of the human race, but God’s Word is examining each of us with the utmost scrutiny, as Hebrews 4:12-13 illustrates, where we read, “For the word of God is quick, and powerful, and sharper than any two-edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.”
And Matthew 24:35 adds, “Heaven and earth shall pass away, but my words shall not pass away.”
In fact, the Lord Jesus Christ, Who is the Judge of all the earth, makes this ominous declaration in John 12:48: “He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day.”
