“Another parable He put forth to them, saying: “The kingdom of heaven is like a man who sowed good seed in his field; but while men slept, his enemy came and sowed tares among the wheat and went his way. But when the grain had sprouted and produced a crop, then the tares also appeared. So the servants of the owner came and said to him, ‘Sir, did you not sow good seed in your field? How then does it have tares?’ He said to them, ‘An enemy has done this.’ The servants said to him, ‘Do you want us then to go and gather them up?’ But he said, ‘No, lest while you gather up the tares you also uproot the wheat with them. Let both grow together until the harvest, and at the time of harvest I will say to the reapers, “First gather together the tares and bind them in bundles to burn them, but gather the wheat into my barn.” ’ ””

“He answered and said to them: “He who sows the good seed is the Son of Man. The field is the world, the good seeds are the sons of the kingdom, but the tares are the sons of the wicked one. The enemy who sowed them is the devil, the harvest is the end of the age, and the reapers are the angels. Therefore as the tares are gathered and burned in the fire, so it will be at the end of this age. The Son of Man will send out His angels, and they will gather out of His kingdom all things that offend, and those who practice lawlessness, and will cast them into the furnace of fire. There will be wailing and gnashing of teeth. Then the righteous will shine forth as the sun in the kingdom of their Father. He who has ears to hear, let him hear!”

Jesus explained this parable in such clear terms. 2 points that I would like to elaborate. The difference between wheat and weed can only be evident when the plants are mature. The wheat which is heavy will droop down whereas the weed's ear will stand up. Hence, it is a perfect example used by Jesus that we are not to judge. It is the reapers, i.e. the angels' duty at the end of this age. Often times, we may impose our value on others and try to fix the person. But, here Jesus exhorted the disciples to leave the weed alone. Yes, we are very tempted to take matters into our hands. The point to learn here is to trust God that He will bring about justice in due course. Secondly, we must take heed that we continue to shine forth for Him and discipline our body and bring it to subjection to God so that we ourselves will not be disqualified to be the sun in the kingdom of the Father (1 Corinthians 9:27). https://twitter.com/EstherOngHC (please click to view a visual)
