A stronghold is JUST THAT -- it has a strong hold on you. Anything that masters you, rather than the other way around. Food, relationships, debt, possessions. Anything from which you don't feel like you can simply walk away, but from which you must be extricated.
And yet Jesus is my stronghold. He has a strong hold on me, and loves me enough to want to be my one and ONLY stronghold.
Though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have
divine power to demolish strongholds.
2 Corinthians 10:3-4
