Not all that is sown in the field is good grain. The fact that men are in the church does not prove them Christians. Then those who have joined the church, but who have not joined Christ, will be manifest. Christ Himself will decide who are worthy to dwell with the family of heaven. He will judge every man according to his words and his works.
Profession is as nothing in the scale.
It is character that decides destiny. The Saviour does not point forward to a time when all the tares become wheat. The wheat and tares grow together until the harvest, the end of the world. Then the tares are bound in bundles to be burned, and the wheat is gathered into the garner of God. Then shall the righteous shine forth as the sun in the kingdom of their Father.
