How do we know our marriage is free from demonic strongholds?

We have been through 10 years of struggle, lukewarm Christians during the roughest portions. We recently had a spiritual awakening and realized we were being demonically attacked. We prayed the blood of Jesus over the walls of our home and forgave each other’s actions/attitudes towards each other. I know Satan hates marriage. I know that our future has us resting in the peace of Jesus, but I don’t know if we have reached that point yet. What does it take? When do we rest?
