Supported in the NT by: Luke 24:44 (ESV) Then he said to them, “These are my words that I spoke to you while I was still with you, that everything written about me in the Law of Moses and the Prophets and the Psalms must be fulfilled.â€
Luke gives here a summary of what Jesus taught the disciples between his resurrection and ascension. The "and" here does not necessarily denote close connection, but only a general continuation of the account and a brief statement of what Jesus said. This might be at different times before his ascension, here is given the substance of his last conversation with his disciples.
It includes the commission. "All things must needs be fulfilled," (complete, done) which had been prophesied of Jesus, or what had been "written in the law of Moses, and the prophets, and the psalms."
This includes all of the Old Testament, for here is mentioned the three divisions into which the Hebrews divided the Old Testament. "The law of Moses" included the first five books, or Pentateuch "The prophets" included the books of Joshua, Judges, First and Second Samuel, First and Second Kings, three of the major prophets (Isaiah, Jeremiah, and Ezekiel), and the twelve minor prophets; "the psalms" included the poetical and all the other Old Testament books sometimes called "the scriptures." John 5:39.
This group contained, Psalms, Job, Proverbs, Song of Solomon, Ruth, Lamentations, Ecclesiastes, Esther, Daniel, Ezra, Nehemiah, and First and Second Chronicles. When Jesus declared that all things must be fulfilled which were written of him, he included the entire Old Testament.
Colossians 2:14 (KJV)
14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross.
Not a soul was ever saved by the law of Moses, because none ever kept it, save Jesus Christ who fulfilled it completely. Persons under the law of Moses were saved, but it was by and through Christ.
No man could be justified by the law, because all sinned and violated the law, and law condemns, and does not justify, or purge from sin. All Jews and Gentiles have sinned, or broken the law, so cannot be saved by law. The law was given to train and prepare men for the reception of Jesus Christ, the promised seed, in whom all nations of the earth should be blessed.
which was contrary to us. The Mosaic law condemned, but could not save, so it "was contrary to us."
and he hath taken it out of the way,—The Mosaic law, including the
commandments written on stones, 2 Cor 3:7 was taken out of the way, nailed to the cross, and is no longer in force as a law in any of its parts. In the new covenant many laws that were in the old covenant were re-enacted and are to be obeyed not because they were in the old, but because they are a part of the new.
nailing it to the cross—It was taken out of the way when Jesus Christ was nailed to the cross, which is saying that the obstacle to forgiveness which is in the law, in the justice of God of which the law is an embodiment, was removed by the death of Christ.
Paul could say: "There is therefore now no condemnation to them that are in Christ Jesus." Rom 8:1. By the cross of Christ, Paul could truthfully affirm that "the world hath been crucified unto me, and I unto the world." Gal 6:14.
