"If you are willing, you can make me clean." Jesus was filled with compassion. He reached out his hand and touched the man. “I am willing,” he said. “Be clean!” (Mark 1:40-41)
The idea of "bad karma" is completely antithetical to scriptural revelation. It implicitly denies the mercy and loving-kindness of God. God is not some tyrant, watching over our shoulders to punish us as soon as we mess up. To be sure, turning our backs on the will of God carries grievous consequences. But the mercy of God is far bigger than that. God is always willing to forgive us, and heal us, and stand us back on our feet. This is precisely what Jesus Christ, who is "the face of God," shows us.
