Heart of Man

From my Bible study guide lesson by Rosetta Lane:

“Grace is radical. It is diametrically opposed to the world system in which we live. Think about it. At school, at play, at work, perhaps even in our own home, we have to perform to be accepted. We have to justify our own existence and do something to earn our keep. It is little wonder that every religious and moral system in the world except New Testament Christianity is based on performance. The heart of man is ever prone to add something of human device to the Divine provision.”
