Physical growth seems to follow automatically from physical birth.
Not so, spiritual growth.
Jesus told Nicodemus very clearly in John 3 that
“I assure you, unless someone is born anew, it’s not possible to see God’s kingdom.”
Jesus doesn’t really explain the metaphor, except to say that we must be born of “water and the spirit.”
These 2 births aren’t exactly identical. There are limits to every metaphor, right?
I suppose one might argue that however growth, either physical or spiritual, requires care and nourishment.
I still think there are limits to the analogy.
Consider, for instance, the story of Jesus restoring sight to a blind man in Mark 8:22-26.
Jesus could just as easily have pronounced him healed, but, instead, he spit in the dirt, made mud, and put it on the man’s eyes.
“Do you see anything?” Jesus asked.
The man replied that he did, but the people looked like walking trees.
So Jesus touched him again, and this time his sight was restored.
Following on the idea that spiritual growth doesn’t automatically follow from a spiritual birth as it seems physical growth does from a physical birth, I want to suggest this:
Perhaps we need a second touch.
Jesus’ first touch clearly made a difference in the man’s life, and in his eyesight. But he couldn’t see clearly.
I know that, over the years, I’ve learned to see things differently than in my first few days after accepting Christ.
As I continue to submit to Jesus’ touch, I pray my sight might continue to improve.
