We are not required to obey the Law of Moses because that Law was nailed to the cross. It was only intended for Israelites anyway. We are required to obey the Law of Christ. You can, for example find every one of the Ten Commandments except the Sabbath Commandment repeated in the New Testament. The reason for that is that the Sabbath was the SIGN of the Old Covenant. Just because the Old Covenant is no longer in force does not mean that the New Covenant does not have Commandments or condemn the same sorts of evil forbidden in the old Covenant. But The law of the Spirit of Life has set us free from the law of sin and death.
Look at it this way. We're not under the Articles of Confederation anymore, but that doesn't mean that laws against murder and sexual immorality are no longer binding.
Cordially,
Why in your opinion did the Master Jesus Christ refer to the Law of Moses on several occasions and teach respect for that Law?
