Hi Fully Restored,
The global church and all church congregations and all Christians all have enemies, satan, demons, and people who hate Christ and his church and Christians.
If you identified the trigger of your dream correctly, the fox probably symbolizes all the enemies of the church. If the part of you and your husband is more personal (not global but closer to home) the fox probably symbolizes any of those enemies in your local congregation. But who the enemy is, does not matter. It is all about the knives and the correct use of those knives (the word of God and proactively using the word of God), as you mentioned yourself.
Irrespective of who our enemies are, we have God and we have the word of God and we call things that are not, into existence. The victory is always ours. If God is for me, who can come against me? Nothing is impossible for God, and obviously for anybody who believes the word of God and actively using the word of God to change his future.
