Scripture
Matthew 12:33 NIV
“Make a tree good and its fruit will be good, or make a tree bad and its fruit will be bad, for a tree is recognized by its fruit.”
Consider
Everyone knows a cherry tree will produce cherries and a walnut tree will produce walnuts. The tree has no choice but to produce fruit according to the nature it was given by its Creator.
When it comes to people, however, our fruit-bearing nature does become a matter of choice. Jesus told his disciples that if we are willing to be grafted into him, then our Creator will transform our nature from the inside out.
