Prophets are an important part of God’s communication to mankind.
Amos 3:7 Surely the Lord GOD will do nothing, but he revealeth his secret unto his servants the prophets.
Through the prophets God reveals his purpose and tells us what he requires of us.
The birth and ministry of Jesus Christ were foretold in detail through the Old Testament prophets.
Matthew 1:22 Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying,
‘The prophet’ occurs 33 times in the King James Version New Testament.
It refers to prophets in the Old Testament.
Sometimes the prophet is named.
Matthew 3:3 For this is he that was spoken of by the prophet Esaias, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
This is a quotation from Isaiah 40
Isaiah 40:3 The voice of him that crieth in the wilderness, Prepare ye the way of the LORD, make straight in the desert a highway for our God.
Sometimes we are expected to locate the prophet by the quotation
Matthew 2:5 And they said unto him, In Bethlehem of Judaea: for thus it is written by the prophet
This is a reference to Micah 5
Micah 5:2 But thou, Bethlehem Ephratah, though thou be little among the thousands of Judah, yet out of thee shall he come forth unto me that is to be ruler in Israel; whose goings forth have been from of old, from everlasting.
We also find reference to ‘that prophet’.
John 1:21 And they asked him, What then? Art thou Elias? And he saith, I am not. Art thou that prophet? And he answered, No.
‘That prophet’ refers to the promise of a prophet like unto Moses.
Deuteronomy 18:18 I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him. 19 And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him.
‘That prophet’ like Moses, to whom they must listen, is Jesus Christ
As Peter explains:
Acts 3:22 For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you. 23 And it shall come to pass, that every soul, which will not hear that prophet, shall be destroyed from among the people.
The writer to the Hebrews says:
Hebrews 1:1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, 2 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;
The future kingdom and millennial reign of Jesus Christ over the mortal population of the earth is foretold by the prophets.
Isaiah 9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. 7 Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this.
Psalms 2:8 Ask of me, and I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession.
