The Wheat and the Tares
In the Parable of the Wheat and the Tares, when the servant sees that the enemy has sown tares among their wheat, he asks the lord if they should try to rip out all of the tares, but the Lord forbids it, because there is a chance that the wheat would get uprooted also. The enemy must have believed that he ruined the crop but he actually made it stronger. I believe there is a second reason the Lord did not want the tares removed. The wheat would now have to struggle and grow faster and stronger and more vibrant now that it was competing for the same soil and water and sunlight. God doesn't allow us to remain with weaknesses or in trials or struggling with temptations for longer than we like on a whim. If He tries to yank out our weakness too soon, He might rip out some of our strengths and virtues at the same time, but also, He knows that if we trust Him and submit like a little child with faith and humility and patience to all that He sees fit to inflict upon us, then we will grow so much more because of our weaknesses and trials and afflictions than we ever could if He simply removed any obstacle the moment it became uncomfortable. God would not allow tares to be planted all around us if He did not have 100% faith that we could reach the sunlight faster and send our roots down deeper than the tares and grow stronger and faster and more vibrant than we ever could have imagined.
