Why don’t Christians listen to Moses?
The simple answer is found in Matthew 17:
This command to listen to Jesus, instead of Moses and Elijah, came from God and is the fulfillment of words God gave to Moses to give to Israel:
Peter quoted this very verse in Acts 3 and applied it to Jesus. There is no doubt that the New Testament teaches Christians are to listen to Jesus. This theme is expanded upon by the book of Hebrews, which opens with this:
God, after He spoke long ago to the fathers in the prophets in many portions and in many ways, in these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world. (Hebrews 1: 1 – 2)
In regards to the differences between what Jesus and Moses taught, we are told this:
The book of Hebrews teaches that if the first covenant of Moses was sufficient, God would have no need of sending Messiah and promising through the prophets a new and better covenant. But since the first covenant was never obeyed by Israel, because of their perpetual sin, something better was needed. This better thing is Jesus and the New Covenant.
And so to summarize our initial examination of this issue, we as Christians do not listen to Moses because the New Testament tells us to listen to Jesus, and instructs us that the New Covenant has replaced the Old Covenant, due to the Old Covenant’s inability to produce the repentance and faith God desired.
