When a seed is planted in the ground it can stay dormant and remain a seed that never grows or produces anything. Or it can take in the nutrients around it, split open, send out roots and stem and grow into a flower or vegetable or fruit. The important thing here is that in order to become something better, the seed has to give up being a seed.
Like the seed, we need to give up what we are in order to become something better. People who cling to the old ways, their old habits, their old likes and dislikes, and remain forever in the boundaries of their comfort zone never grow into something better.
So, let go. Let go of the past. Let go of the old you, and let God do His work in you. Let the old you die and the new you come forth bearing wonderful fruit!
