but also not with their own good

"Who is pure in heart? Only those who have completely given their hearts to Jesus, so that he alone rules in them. Only those who do not stain their hearts with their own evil, but also not with their own good. A pure heart is the simple heart of a child, who does not know about good and evil, the heart of Adam before the fall, the heart in which the will of Jesus rules instead of one’s own conscience.… A pure heart is pure of good and evil; it belongs entirely and undivided to Christ; it looks only to him, who goes on ahead. Those alone will see God who in this life have looked only to Jesus Christ, the Son of God. Their hearts are free of defiling images; they are not pulled back and forth by the various wishes and intentions of their own. Their hearts are fully absorbed in seeing God. They will see God whose hearts mirror the image of Jesus Christ."
