Imagine you decided, “I'm going to spend the next hour praying to God and dealing with this particular matter with my Father in heaven,” and suddenly a friend comes visiting. Do you leave your prayer to answer your friend or do you tell your friend to wait for you? That's what “shut your door” means. You can open your door to a visitor or other distractions or you can open your door to God. But you can shut your door and say, “Not now, I have a business with God at this time” and shut the door on every other thing and then you get blessed.
Some years ago, a member of our church came to see me for counsel and she was told that I was praying and I had been there for a number of hours. Before I finished, she had left. The person wrote me and said, “Pastor, I came to see you and you didn't come out.” I said, “I was receiving from the presence of God what makes me your pastor. I can't leave the presence of God because if I function as a human being like you, I can't be a blessing to anybody. But with the anointing of God on my life, I can be a blessing to you.” I had to shut my door like that.
That's what it means to shut your door, to pray to your Father which is in secret and your Father who sees in secret shall reward you openly. The rewards include answers to prayers, a peaceful home, a powerful ministry, the anointing of God and signs and wonders as it was in the life of Jesus. 
PRAYER: Lord, I choose to shut the door to every distraction and open to You. I need You every hour, I choose the peace that Your tender voice affords me in Jesus’ name. Amen!
