From time to time, we are asked about the place of the 10 Commandments in modern times. Put simply, we do not live under the 10 Commandments today because we are living under the New Testament.
The book of Hebrews (7:12-14, 8:13, 9:15-17) makes it clear the Old Testament is done away. The Old Testament, including the 10 Commandments, was given to a specific group of people (Deut. 5:2-5). Exodus 19-20 tells us that the 10 Commandments were given to the Jews (Ex. 19:3-6).
