Question:
Is it sin for a man or woman to step out of their role?

Answer:

It is if it is done purposely—this is disrespect to the Lord.  God’s glory is at stake.  God’s Word is inspired—He wouldn’t have included something in Scripture if it wasn’t important.  This is why we need to study these principles and understand them.  It was a privilege for the Lord Jesus to honor God.  It should be a privilege for us to honor God by doing what He has asked us to do.
