the following illustration hits home .... that Christianity isn't just about a one time thing but it is about ongoing transformation. That Change should and is happening. As Romans 12 says:
"1-2 So here's what I want you to do, God helping you: Take your everyday, ordinary life—your sleeping, eating, going-to-work, and walking-around life—and place it before God as an offering. Embracing what God does for you is the best thing you can do for him. Don't become so well-adjusted to your culture that you fit into it without even thinking. Instead, fix your attention on God. You'll be changed from the inside out. Readily recognize what he wants from you, and quickly respond to it. Unlike the culture around you, always dragging you down to its level of immaturity, God brings the best out of you, develops well-formed maturity in you. " (The Message)
“You have perhaps heard the story of Spurgeon, the great pastor in the nineteenth-century London, who was walking down the street one day when a man who was drunken and leaning on the lamppost yelled out to him, ‘Hey, Mr. Spurgeon, do you remember me?’ And Spurgeon replied, ‘No, why should I?’ The man said, ‘ Because I’m one of your converts.’ To which Spurgeon replied, ‘Well, you must be one of mine; you’re certainly not one of the Lord’s.’”
