Matthew 26:40-41

40 When he came back to his disciples, he found them sound asleep. He said to Peter, "Can't you stick it out with me a single hour?

41 Stay alert; be in prayer so you don't wander into temptation without even knowing you're in danger. There is a part of you that is eager, ready for anything in God. But there's another part that's as lazy as an old dog sleeping by the fire."
