For me, it’s just gotta be heart.

How can we put God in a book and tell him to stay there?

Sure, there are facts we become aware of - they are few: Jesus, the Son of God, crucified for my redemption, resurrected for my eternality. But where we store these facts, where we plant those seeds, determines whether they will grow or not. The mind is rocky soil, mixed with so much thorny, puffed up and prideful proof of righteousness, that facts planted there often grow stunted and produce haughty fear-fruit, if they even take root at all. But the heart, what rich soil unhindered by vanity and the pretensions of intelligence, that produces a lush harvest of love for our brother Jesus. What trust, what longing, what unconcern for details, what abandon, that follows him even to death. The head cannot conceive of such unsafe behavior and instinctively condemns and shuns the rebellious, libertarian heart.
