I just have this on my heart to share because your situation is so dear to me.
I see this dream as means of God getting the faith to arise in your heart to fight for your family.
God said He would give you the desires of your heart as you Delight yourself in Him.
His desires become your desires.
I too, had the desire to fight for my family.
I too, had a very legalistic mother in law.
But God revealed to me who I was in Christ and the authority I had as His child.
This is what I’ve learned. The devil can’t have what we don’t give him.
I would walk through my home declaring that the GREATER ONE resides here.
I would pray that eyes were opened to that.
Jesus is far Greater than religion and His Love annihilates strongholds.
I was stern by the Spirit, but chose to walk in love even at my own hurt.
My marriage is Fully Restored to this day.
We are stronger than we’ve ever been as a couple and individually by the Spirit.
We fought for the covenant we made, and Yes, as long as there is one fighting, YOU AND GOD ARE THE MAJORITY.
I was reminded just yesterday of how the prophet Elishas servant was fearful about the overwhelming army outside… we often feel that way as well, but The Word in Elisha was this:
THERE IS MORE WITH US THAN THERE IS WITH THEM.
You are a child of the a Most High.
His promises to you are Yes, and Amen, through Jesus.
You are already victorious.
I see your boss, as the Savior, reminding and giving you the authority.
