Deut 20-22 God has mandated that his people were to be pure and holy and that is why He gave them the Ten Commandments and sundry rules and laws. So much to remember! And then there is the question that always arises today is why God wanted them to destroy so many people. The answer is given: these were nations that were given time after time to repent and turn to God but they chose to worship and praise the gods of silver, gold, bronze etc. They, like Belshazzar, knew what God wanted but they willingly chose to ignore God’s way. [Dan. 5] Has God revealed what He wants today? The answer is a resounding yes! Romans 1:20 says that creation screams His attributes and His perfect creation.
However, just like then, people today do not want God, they want to be gods.
In Egypt, they had taskmasters that kept the peace. In the wilderness, Moses kept the peace. Now they were entering uncharted territory. Who will keep the peace now? That is why God gave them the Ten Commandments and the Priesthood. These sundry rules will guide them in times they had questions.
God is asking all of us what we desire. Do we desire what God desires; purity, righteousness, and holiness?
