In Matthew 13:36-43, Jesus explains the Parable of the Wheat & Tares. Many use this parable to justify a mixed church membership, composed of believers and unbelievers. This justification is unfounded and, to put it bluntly, dead wrong. Not only does it contradict the promised realities of the New Covenant (Jeremiah 31), it ignores Jesus’ own explanation of the parable. In Matthew 13:36, Jesus says, “and the field is the world…” Hence, the field in which the wheat and tares are allowed to grow is NOT the church (or New Covenant community).
36 Then he left the crowds and went into the house. And his disciples came to him, saying, “Explain to us the parable of the weeds of the field.” 37 He answered, “The one who sows the good seed is the Son of Man. 38 The field is the world, and the good seed is the sons of the kingdom. The weeds are the sons of the evil one, 39 and the enemy who sowed them is the devil. The harvest is the end of the age, and the reapers are angels. 40 Just as the weeds are gathered and burned with fire, so will it be at the end of the age. 41 The Son of Man will send his angels, and they will gather out of his kingdom all causes of sin and all law-breakers, 42 and throw them into the fiery furnace. In that place there will be weeping and gnashing of teeth. 43 Then the righteous will shine like the sun in the kingdom of their Father. He who has ears, let him hear.
