The old testament is completed in the new.
The new testament is incomplete without the old.
We have one God, one bible and one truth.
Here are just three examples of misunderstood verses with quotes from the old testament because of the false notion that one can be a new testament only Christian.
Romans 9:24-25 is from Hosea 1:9 where the phrase “not a people” is a description of the House of Israel, the Ten Northern tribes, who became known in scripture as Nations [Gentiles] after their divorce from God. Scripture later calls those people “Sons of the Living God” or Christians. The bible defines its own terms.
Romans 11:2. The concept of the fulness of nations is from Genesis 48:19 where the descendants of Joseph would become a multitude (fulness) of Nations.
1 Peter 1:16 is from Leviticus 11:44 where the context makes Peter’s meaning of holy to be understood.
The writers of the new testament only knew the old testament. The Holy Spirit was given to the apostles so that they could, among other things, fully understand the Law and Prophets.
Luke 24:44-45 “And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me. Then opened he their understanding, that they might understand the scriptures,”
When did Christ give the Holy Spirit to the apostles? Christ gave the Holy Spirit to the apostles in John 20:21-22.
“And Jesus said to them again, May peace be with you! As the Father sent me, even so I now send you. And when he had said this, breathing on them, he said to them, Let the Holy Spirit come on you”.
The baptism of the Holy Spirit in Acts 2 was a special event. It is never repeated in the rest of scripture.
