Paul Miller, in his book A Praying Life:
Imagine that your prayer is a poorly dressed beggar reeking of alcohol and body odor, stumbling toward the palace of the great king. You have become your prayer. As you shuffle toward the barred gate, the guards stiffen. Your smell has preceded you. You stammer out a message for the great king: ‘I want to see the king.’ Your words are barely intelligible, but you whisper one final word, ‘Jesus. I come in the name of Jesus.’ At the name of Jesus, as if by magic, the palace comes alive. The guards snap to attention, bowing low in front of you. Lights come on, and the door flies open. You are ushered into the palace and down a long hallway into the throne room of the great king, who comes running to you and wraps you in his arms.
The name of Jesus gives my prayers royal access. They get through. Jesus isn’t just the Savior of my soul. He’s also the Savior of my prayers.
