Could it be a spiritual warfare?

It always happens to me every time I'm on for worship.

Work would be crap and there would be insane problems that never happened before.

Our conflict started only started this year, just shortly after Dave went into ministry.

If so, and I believe so, then what we have to do is to pray together, fight together, and not let the devil have the victory.

Jesus rebukes the devil. He fights for us.
