Get alone. You'll pray a different prayer when you're by yourself than you do when you're in the public. Slip alone, all of you; go out and just have a real secret meeting place, where you and the Lord meet several times a day and pray.
I don't sleep very much at night, always in prayer. Nighttime, when all demon powers shut down towards morning. When they're not roaming, that's the time the Holy Spirit moves in and talks to me. Go early if you want to pray; rise up early.
