“If what a prophet proclaims in the name of the Lord does not take place or come true, that is a message the Lord has not spoken. That prophet has spoken presumptuously. Do not be afraid of him” (Deut. 18:22).
“But the prophet who prophesies peace will be recognized as one truly sent by the Lord only if his prediction comes true” (Jer. 28:9).
“When all this comes true - and it surely will - then they will know that a prophet has been among them.” (Ezek. 33:33).
“The Lord was with Samuel as he grew up, and he let none of his words fall to the ground. And all Israel from Dan to Beersheba recognized that Samuel was attested as a prophet of the Lord” (1 Sam 3:19).
“I declared the former things long ago and they went forth from My mouth, and I proclaimed them. Suddenly I acted, and they came to pass.… Therefore I declared them to you long ago, before they took place I proclaimed them to you, lest you should say, ‘My idol has done them, and my graven image and my molten image have commanded them’” (Isaiah 48:3, 5)
“For 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” (2 Pt. 1:21).
2 Pet. 1:19 “We have also a more sure word of prophecy. ”God's message, became God's Word and had a purpose for the future. “Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying ...” (Mt. 1:22). God spoke it, by using the prophet's mouth--God's message and God's Word, but it was delivered by way of a human mouth. Prophecy is inspired speech! It is nothing less than the Word of God in spoken or written form.
In Ephesians 2:20, the New Testament apostles and prophets were foundational: “And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone.” A foundation is laid only once to begin a building project. You do not keep laying a foundation. These men (*apostles and prophets) were foundational -- through them that we received the New Testament Scriptures for all generations.
The Bible makes it clear that a prophet is someone who speaks on God’s behalf to the people and there is no inaccuracy in his words. When the prophets of old got their message from God, it was perfect, free from any error. They spoke confidently knowing that what they said God would bring to pass.
“Behold, the former things have come to pass, And new things I declare; Before they spring forth I tell you of them” (Isa. 42:9) Because of God’s covenant relationship to the nation of Israel He specifically chose to speak to them from among their own.
“Remember the former things long past, for I am God, and there is no other; I am God, and there is no one like Me, declaring the end from the beginning and from ancient times things which have not been done… “ (Isaiah 46:9, 10).
