We say people can come into the Kingdom through grace, but once they're in, we switch from grace to duty, obligation, and pressure. Though we preach that you can't contribute a thing to your own salvation and that it's all God's gift for you, once you're "safe" however, you'd better keep up and step up. This fallacy is why Paul had to be pointedly firm with God's family in Galatia when he said: "Are you so foolish? After beginning with the Spirit, are you now trying to attain your goal by human effort?" In today's distorted Christianity, you can come in under God's power, but once you're in the door, it's about your effort to make this thing work. Grace dissolves into exertion. And because you can never do enough, exertion soon turns to shame: "I know I'm supposed to be serving, loving, thinking pure thoughts, but I just can't. It goes well for a while, then I blow it... again." Soon, shame turns into resignation: "I no longer want to try harder. I feel like giving up." And God asks the Church, "Why do you turn my glory into shame?!"
