Were you ever in all your life sorry for your sins?

"Give me leave to ask you, in the presence of God, whether you know the time, and if you do not know exactly the time, do you know there was a time, when God wrote bitter things against you, when the arrows of the Almighty were within you? Was ever the remembrance of your sins grievous to you? Was the burden of your sins intolerable to your thoughts? Did you ever see that God's wrath might justly fall upon you, on account of your actual transgressions against God? Were you ever in alI your life sorry for your sins? Could you ever say, My sins are gone over my head as a burden too heavy for me to bear? Did you ever experience any such thing as this? Did ever any such thing as this pass between God and your soul? If not, for Jesus Christ's sake, do not call yourselves Christians. You may speak peace to your hearts, but there is no peace. May the Lord awaken you, may the Lord convert you, may the Lord give you peace." 
[George Whitefield, from a sermon titled, "The Method of Grace". Quoted in Whitefield Gold, compiled by Ray Comfort.]
