In the parable of the wheat and the tares in Matthew chapter 13, our Lord unveils the remarkable secret that God is purposely causing sons of the Kingdom and sons of the Adversary to not only look alike, but to grow up together. This is a distressing situation until one realizes that God is doing this on purpose. This has been the situation now for 2,000 years, but the time is coming—spoken of in the parable as "the conclusion of the eon"—when God will at last dramatically distinguish those who are His and those who are not.
