Prophet, Prophecy Definition
God speaking through His servants.
God appointed priests to supervise the worship of His people Israel, but God also spoke to the people through the prophets, who were more concerned with the moral and spiritual character and activities of the people. The prophets continually encouraged Israel to trust God and to be obedient, not to neglect Him, and not to worship the pagan idols of the surrounding nations.
Today we may think of prophets as people who can foretell the future, but this was only a power given to them by God to prove that the message they gave was truly from Him. There were short-term and long-term prophecies. For example, in the short term, Elisha prophesied that the siege of Samaria would end the following day, and it happened (in 2 Kings 7). In the long term, most of the prophets write of times yet future when God's Kingdom will be in the earth again ( Isaiah 35, Jeremiah 33, Ezekiel 20).
Micah 4 v2 'And many nations shall come, and say, Come, and let us go up to the mountain of the LORD, and to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for the law shall go forth of Zion, and the word of the LORD from Jerusalem.'
