In the beginning God created the heavens and the earth. (Genesis 1:1)

It is believed that Moses wrote the Book of Genesis. Moses foretold that God would send a prophet like him.

The LORD your God will raise up for you a prophet like me from among you, from your countrymen; to him you shall listen. (Deuteronomy 18:15)

God gave Moses and the Israelites the law and made the (old and conditional) covenant with them. God promised them righteousness if they kept the law. None of the Israelites could gain righteousness. But there were people under the new covenant even in the OT beginning from Abel. Their righteousness was from faith. That faith is a gift from God and is from the heart of flesh that knows, understands, and loves God. Adam did not have the heart of flesh because he wanted to become like God and rebelled against Him. He relied on his own wisdom. Most of the Israelites were not given the heart and perished.

Yet to this day the LORD has not given you a heart to know, nor eyes to see, nor ears to hear. (Deuteronomy 29:4)

If the new covenant is only the continuation of the old covenant, God would not have made the two tablets breakable.

And it came about, as soon as Moses approached the camp, that he saw the calf and the people dancing; and Moses’ anger burned, and he threw the tablets from his hands and shattered them to pieces at the foot of the mountain. (Exodus 32:19)

The new and eternal covenant is not breakable because its life is in the only begotten Son of God. The Father never forsakes the Son. The Israel nation, the law, and the old covenant were only shadows to the real one. They indicated the coming of Christ. They existed to tell people that the Messiah must come. Christ’s beginning is not 2000 years ago. The Son’s beginning is from eternity like the Father. The Son is the mediator of the new covenant. This tells us that the new covenant is what God planned before creation. Although it is called “new”, it is the eternal covenant that was planned before creation because its life is in the Son who is from eternity.

Some ignorant theologians view that John 1:1-18 shows the influence of Greek philosophy. They want to interpret everything by human reasoning and are proud of their knowledge in philosophy. They speak nonsense because they do not understand what the Bible teaches. One with the Holy Spirit understands the Bible. The knowledge of God inevitably leads to John 1:1.

In the beginning was the Word, and the Word was with God, and the Word was God. (John 1:1)

John emphasizes the fact that Jesus Christ is from eternity just like the Father and is equal with Him. He also tells us that Christ is not above the Father or is separate from Him. This teaches us a lot. At present, Christians worship Jesus as if He saved us from the hands of the Father. They love to make a song about Jesus but refuse to sing in God’s words. They preach what Jesus has done but do not speak about Him being one with the Father. Christ did exactly what the Father wanted Him to do. But people want to worship a man called Jesus. While they say they love Jesus, they don’t do what He taught.

God makes everything new at the end because the old order of things passes away. As we read Revelation 21 and 22, we conclude that everything was made for and through the Son. The old things demand the new things. But the new things are not the continuation of the old things. Rather, the old things are shadow of the reality.

And He who sits on the throne said, “Behold, I am making all things new.” And He said, “Write, for these words are faithful and true.” (Revelation 21:5)

He is the image of the invisible God, the firstborn of all creation: for by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones, or dominions, or rulers, or authorities—all things have been created through Him and for Him. He is before all things, and in Him all things hold together. (Colossians 1:15-17)

John the Baptist starts public ministry before Christ. His coming was written in Malachi 3:1. Malachi is the last book of the OT. In the book, God spoke of the covenant of the Levi and the restoration of the priesthood. Although it is restoration, true priesthood of the saints started only when Christ resurrected. The eternal and only High Priest leads our way. John came to testify that the OT is all about the Son and the new covenant that He brings. However, people like the old more than the new.

And no one, after drinking old wine, wishes for new; for he says, ‘The old is fine.’ (Luke 5:39)
