A prescribed way is a laid down rule. It is possible to ignore prescribed ways and do things on the basis of need, convenience, practicality and success.
For example, God expects pastors to feed His people with knowledge in a church. A pastor can focus on miracles, which is a legitimate gift instead of teaching. A woman can be the head of the house, because she is economically more empowered, although the man has been appointed head.
Some of these things may sound logical, but they may be breaking divine protocol.
In the time of David, only Levites were supposed to carry the ark. Uzzah, who was not a Levite wanted to help by carrying the ark and was slain by the lord.
1 Chronicles 15:2
Then David said, “No one but the Levites may carry the ark of God, because the Lord chose them to carry the ark of the Lord and to minister before him forever.
1 Chronicles 15:13
It was because you, the Levites, did not bring it up the first time that the Lord our God broke out in anger against us. We did not inquire of him about how to do it in the prescribed way.
We must be careful when dealing with the lord, because the fact that something is good or helpful does not necessarily mean it is the prescribed way.
Let’s follow divine order and protocol to avoid diving judgment!
