Look at the Sugar Snap peas instinctively looking for something to cling to. It is amazing to me that God programmed this little plant, that doesn't even have a brain, to know there was something out there, much bigger than itself, that would help it grow. All it has to do is grab on.
I think God programs us to know the very same thing. There is a cross out there that we are suppose to cling to and will help us with living life and growing a new nature.
Of course, every good seed has found Living Water, which helps it grow. Matthew 13, Mark 4 and Luke 8.
"But he who received seed on the good ground is he who hears the word and understand it, who indeed bears fruit and produces: some a hundredfold, some sixty, some thirty." Matthew 13:23.
