Parable of wheat and tares

This parable I believe is very familiar amongst Christians. I however for the first was able to grasp the answers to all my why's? So one of the questions I used to ask when reading this passage was if it's already yielding fruit and you can clearly see the tares, why not pluck it up? How can wheat magically stop producing wheat, and how can a tare suddenly produce wheat? So a few weeks ago God made this clear to me. Sometimes babes in Christ start out shaky. Their fruit is not well formed at this stage so they appear to be still worldly. As they mature in God so does their fruit in God begin to mature. So a person that was once a tare can morph into wheat. The same thing with a saint who starts off being very productive in the kingdom of God. Things can happen that causes them to backslide or just sit still in the things of God. The once mature saint can go from a productive blade of wheat to a tare. Since life can cause either of these transformations to fluctuate Jesus let the disciples know neither the wheat or tare will be harvested until God gives the Angel's command to do so. It is not our job to pluck anyone up. It is our job to cultivate grounds so that fruitfulness is possible. God will inspect the fruit later.
