Introduction

Why don’t we add instruments to that?

  • The simple answer is: because God does not authorize us to do so.

God didn’t say NOT to.

God didn’t say NOT to … carry the ark on an ox cart.

God didn’t say NOT to … appoint a priest from Judah.

God didn’t say NOT to … offer strange fire.

God didn’t say NOT to … preach circumcision.

If God only authorized: Then that leaves everything else unauthorized:
The Kohathites using poles to carry the ark on their shoulders Ox cart, etc.
Priests to comes from the tribe of Levi Priests from Judah, etc.
A certain fire Some other fire, etc.
Preaching the gospel of Christ Preaching circumcision, etc.
Singing as musical worship Instruments, etc.

Instruments are just aids, like pitch pipes or song books.
