God gave the gift of his righteous Ten Commandments to the children of Israel after their Egyptian bondage. Each of these laws are restated, either in word or meaning, in the Gospels or the rest of the New Testament. In fact, we do not have to go far before we encounter the words of Jesus regarding the laws and commandments of God.
Near the very beginning of Jesus' well-known Sermon on the Mount he states something that is often twisted, or simply forgotten, by those who wish to do away with the commandments. He states, "Do not think that I have come to abolish the Law or the Prophets; I did not come to abolish, but to fulfill . . . until the heaven and the earth shall pass away, one jot or one tittle shall in no way pass from the Law (God's commandments, judgments, statutes, and so on) . . . (Matthew 5:17 - 18).
The 'jot' mentioned in the above verse was the tinest Hebrew or Greek letter of the alphabet. The 'tittle' is a very small stroke or mark added to some letters of the Hebrew alphabet in order to distinguish one from another. From Jesus' statement we can only conclude that since heaven and earth are still here, God's commandments have not been "done away with" but are still in effect!
The apostle John, in the last book of the Bible, makes a crystal clear statement regarding the importance of God's law. Writing about truly converted Christians who live in the time just before Jesus returns to earth he states they 'keep the commandments of God' AND they also have faith in Jesus Christ (Revelation 14:12)! John is stating that both obedience and faith can coexist!
Listed below are God's commandments as found in the book of Exodus, chapter 20. Along with each one is where they are repeated, either exactly or in principle, in the New Testament.
