And he said, “The kingdom of God is as if a man should scatter seed upon the ground, and should sleep and rise night and day, and the seed should sprout and grow, he knows not how. The earth produces of itself, first the blade, then the ear, then the full grain in the ear. - Mark 4:26-28
But what we have noticed is that when there is no string or branch to cling to, it withers and dies. Its limbs grow scrawny, they dangle and their ends just die. As Jesus taught in the gospel of St. John:
“I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing. If you do not remain in me, you are like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. If you remain in me and my words remain in you, ask whatever you wish, and it will be done for you. This is to my Father’s glory, that you bear much fruit, showing yourselves to be my disciples." ~ John 15:5-8
All of nature images the Divine Plan of God in some way, and the Parables of Jesus point to this fact. God is so exceedingly magnificent - He will never cease to amaze us. Deo Gratias!
