As a part of the tree of Life, God provides a home for the fruit bearing believer. Those branches that believe in him are fruitful. The unproductive branches who do not believe are separated from God.
In our separation we are not nourished by the care of God but rather our personal care. We can separate ourselves or we can be pruned for growth by God. In his pruning correction from God helps promote our spiritual growth.
Anything that is not of God will be cut off at the point of contact with the branches of the tree. Unproductive fruit can infect the other branches of the tree. God brings good and bad into our lives to feed us at all times, we must be growing in the word to recognize the good from the bad to assess what we need to survive with him.
Sunshine and rain help feed our cause at all time to bear fruit. To gain the spirit of the fruit we must be near God to be fed at all times. Your heart for God is found in your harvest
