1 Peter 1:23

Having been born again, not of corruptible seed but incorruptible, through the word of God which lives and abides forever.

A seed has everything in it to get it started for growth. Any corruption of the seed stops the growth of the seed and its ability to produce. Jesus, the word comes inside us and makes us into an incorruptible seed. Being born again gives us a chance every day to grow in the word of God. The bible says when we do that, the word takes root and causes us to grow and flourish.
