Who is one who announces good news?

This is an important question; the Bible tells us that the very feet of him that brings good news are beautiful, and that the one who cries in the wilderness, helps prepare the way of the Lord. Isaiah 52:7 How beautiful upon the mountains are the feet of him that bringeth good tidings, that publisheth peace; that bringeth good tidings of good, that publisheth salvation; that saith unto Zion, thy God reigneth! 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. Elijah Malachi 4:5 Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the LORD: John the Baptist Luke 1:76 And thou, child, shalt be called the prophet of the Highest: for thou shalt go before the face of the Lord to prepare his ways; Matthew 17:10-13 And his disciples asked him, saying, Why then say the scribes that Elias [Elijah] must first come? And Jesus answered and said unto them, Elias truly shall first come, and restore all things. But I say unto you, That Elias is come already, and they knew him not, but have done unto him whatsoever they listed. Likewise shall also the Son of man suffer of them. Then the disciples understood that he spake unto them of John the Baptist. Jesus' Disciples Acts 1:8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. Jesus Himself Matthew 9:35 And Jesus went about all the cities and villages, teaching in their synagogues, and preaching the gospel of the kingdom, and healing every sickness and every disease among the people. Every Christian Mark 16:15-16 And he said unto them, Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved; but he that believeth not shall be damned. ---- Anyone Christian who goes to the people of all the nations announcing the Good News about God's Kingdom, with Jesus Christ as King. Matthew 24:14--'And this good news of the kingdom will be preached in all the inhabited earth for a witness to all the nations; and then the end will come'. Matthew 28:19,20--'Go therefore and make disciples of people of all the nations, baptizing them in the name of the Father and of the Son and of the holy spirit, teaching them to observe all the things I have commanded YOU. And, look! I am with YOU all the days until the conclusion of the system of things." Romans 10:13-15--'For "everyone who calls on the name of Jehovah will be saved." However, how will they call on him in whom they have not put faith? How, in turn, will they put faith in him of whom they have not heard? How, in turn, will they hear without someone to preach? How, in turn, will they preach unless they have been sent forth? Just as it is written: "How comely are the feet of those who declare good news of good things!" Jehovah's Witnesses, are following Jesus' commands to 'announce' or 'preach' the Good News, individually, to people of all the nations, making disciples. All of Jehovah's Witness preach to everyone who will listen so that each one will be trained to go and 'preach the Good News' to still others.
