When the leadership of a community adopts Paul's focused goal, a miraculous loving dynamic begins to transform a congregation. First He pinpoints two negatives that are absent. They are a judgmental spirit and a condemning attitude. That constitutes love from a pure heart, clean mind and strong faith. One law of the harvest is that everything produces after its kind.
Apple trees produce apples, cherry trees produce cherries.
In scripture our lives are likened unto fruit trees. Positive lives produce positive fruit. Negative lives produce negative fruit. Forgive and give and you'll have a forgiving, giving family. Judge and condemn and your children will grow up to judge and condemn you.
