What kind of prayer would cause the Son of God to be stopped in His tracks? You will find many types of prayer in the gospel of Luke and the eighteenth chapter, but there is only one prayer that caused Jesus to stand still. This type of prayer begins in the heart of a beggar. It's a heart that understands its utter and dyer need. This is the heart that cries out in faith "Jesus Son of David have Mercy on me!" God's responds to this cry because His heart is filled with mercy and grace. We don't have to wrestle a blessing from God.
