Lev 19-21 One thing we must remember as we study this marvelous book of “you must not and you must” is that these are the very words of God. They were written that we might be instructed in not what we think is right but what God thinks is right. As Ken Boa said “God only has to say “no” once for something to be wrong.” God’s purpose is that His people who are set apart for him are to be holy because he is holy.
In addition, they were written so that we remember that “All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness so that the man of God may be adequate, equipped for every good work.” [2 Tim 3:16]
God was preparing to send the Israelites into a polluted nation. He did not want them polluted with what he considered abominable and thus why he spent an entire book explaining the “must not’s and the musts.” It is because He loved them and He loves us that these are written “for our instruction.”
Today read these chapters with those thoughts in mind.
