God, who at various times and in various ways spoke in time past to the fathers by the prophets, has in these last days spoken to us by His Son, whom He has appointed heir of all things, through whom also He made the worlds.
The Bible is a collection of words that God has given to mankind. In the Old Testament, God spoke audibly voice to men and women like Adam and Eve, Noah, Abraham and Moses. However, God spoke mostly to Israel or the Gentiles through His prophets. Thus we see the prophets who spoke to the kingdoms of Judah and Israel, as Elijah, Isaiah and Jeremiah; Jonah who brought the message of God to the Assyrians in Nineveh; or Daniel to the Babylonians and Persians.
In the New Testament, a prophet, John the Baptist, he announced the imminent arrival of the Messiah. Luke 3:16 says: John answered, saying to all, “I indeed baptize you with water; but One mightier than I is coming, whose sandal strap I am not worthy to loose. He will baptize you with the Holy Spirit and fire. After John the Baptist, God sent His powerful message to humanity through His Son Jesus Christ. That message from God is mostly collected in the four gospels.
One of the most notorious speeches of Jesus is the Sermon on the Mount which is in Chapter 5 of Matthew. Most people are familiar with the Beatitudes that are part of this sermon, but that was not all He said there the Son of God. Let’s turn to Matthew 5:17-19: Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill. For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled. Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven; but whoever does and teaches them, he shall be called great in the kingdom of heaven.
This part of the teachings of Jesus Christ is rarely preached in churches. It is much easier to bring people a message that things will go well if they do meet Christians than teaching that God has ordained. Compliance with the law is carried out in the same Jesus, who became sin without sin to pay for ours. No human being is able to comply with the Law of God, only Christ can do. Therefore He is the Lamb of God who takes away the sins of the world.
God also spoke through His Son in John 3:16-17: For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. Here is the key to the salvation of every human being on Earth.
The words that God has spoken to the world in these last days through His Son can be summarized that the human being is unable to save himself. Therefore, only a perfect being as Jesus Christ is able to promote our salvation. It is necessary to believe in Him for eternal life. God bless you.
