It is foolish to dismiss studying different parts and subjects in the Bible, especially prophetic scriptures, as not being necessary for one's spiritual maturity. The last few verses of Scripture warn ALL humans that how God's words are treated has serious consequences.
"For I jointly testify to everyone who hears the words of the PROPHECY of this book, that if anyone adds to these things, God shall add to him the plagues that are written in this book. And if anyone takes away from the words of the book of this PROPHECY, God shall take away his part from the book of life, and from the holy city, and from the things that are written in this book." (Revelation 22:18 - 19)
God exists and can do as He wills
The second and third reason regarding the important of this subject is that it is a proof of God's existence and that he has the power to do as he wills. The accurate fulfillment of predictions in the Bible, in every detail within a specified time frame, testify that a divine Creator does exist and that he has the power to influence people's lives and foreordain events on planet earth.
God accurately predicted in advance, and made come to pass, the rise of world empires like Persia and Rome (Daniel 2:32 - 33, 40 - 41, 7:7, 8:3 - 4, 20). God also prophesied the rise of the Greek empire through Alexander the Great. Additionally, he foretold that NOT ONE of Alexander's family would rule the empire after his death and that it would split into FOUR pieces (Daniel 8:21 - 22). Please see our article on all the prophesied kingdoms foretold to exist from Babylon forward entitled "World Empires from Babylon to the Beast."
Jesus is the divine Messiah
The accurate prediction of his own death and the exact length of time he would be dead was the ONLY sign Jesus gave religious leaders that he was the Messiah (Matthew 21:38 - 40).
Jesus testified of his own divinity during his unjust trial when he foretold what the hateful religious leaders, who wanted him dead, would soon see.
(the High Priest asked Jesus during his trial) 'Are you the Messiah, the Son of the Blessed God?' 62 'I am,' answered Jesus, 'and you will all see the Son of Man seated at the right side of the Almighty . . . ' (Mark 14:61 - 62)
God has a plan
Biblical prophecy can testify to the plans God has for all mankind. For example, the Bible predicts at least two resurrections from the dead. The first one shows God has planned a reward to those who believe in him (1Thessalonians 4:16, Revelation 20:6). The second resurrection tells us God will soon offer ALL humans a full chance at understanding and receiving salvation.
"The hand of the LORD was on me, and brought me by the Spirit of the LORD, and set me down in the midst of a valley, and it was full of bones . . ."
"Thus says the Lord GOD to these bones, "Behold, I will cause breath to enter into you, and you shall live. And I will lay sinews on you, and will bring up flesh on you, and cover you with skin, and put breath in you, and you shall live. And you shall know that I am the LORD."
"And He (God) said to me (Ezekiel), "Son of man, these bones are the whole house of Israel."" (Ezekiel 37:1, 5 - 6, 11, see also John 5:28-29, Revelation 20:5, 13)
Warnings to the converted
In what is referred to as the Olivet prophecies, Jesus warns those who believe in him about the deceptions, false Christs and prophets, and other things that will come in the End Time.
4 Jesus answered (to his disciples who asked him when the end time will come), 'Watch out, and do not let anyone fool you. 5 Many men, claiming to speak for me, will come and say, 'I am the Messiah!' and they will fool many people. 24 For false Messiahs and false prophets will appear; they will perform great miracles and wonders . . .' (Matthew 24:4 - 5, 24)
Warnings to all humans
Bible Prophecy is, many times, God's advance warning that there are very REAL consequences to the choices we make and actions we take in this life. Nobody ultimately "gets away with" sinning. What we do will, eventually, catches up with us.
"Some men’s sins are open to public view, going before to judgment; and some men’s sins follow after." (1Timothy 5:24)
God used Jonah the prophet to warn ancient Nineveh that its sins would soon bring his judgment upon them (Jonah 1:1 - 2, 3:4). In a rare occurrence that warranted its mention by Jesus (Matthew 12:41), the people of Nineveh heeded the prophetic warning of their destruction and repented. Their actions CHANGED the prophetic declaration of their demise.
5 The people of Nineveh believed God’s message (from Jonah the prophet). So they decided that everyone should fast . . . 10 God saw what they did . . . So he changed his mind and did not punish them . . . (Jonah 3)
God has prophetically warned all human beings that if they REFUSE to repent of their sins His final judgment will come upon them.
'Watch now,' the Lord Almighty declares, 'the day of judgment is coming, burning like a furnace. The proud and wicked will be burned up like straw; like a tree, they will be consumed - roots and all.' (Malachi 4:1, TLB)
God has placed prophecies in his word for many important reasons. It therefore behooves us to take Bible prophecy seriously and learn what it can teach us. Such knowledge can only help us in our daily walk with God.
