“And when the king came in to see the guests, he saw there a man which had not on a wedding garment: 12And he saith unto him, Friend, how camest thou in hither not having a wedding garment? And he was speechless. 13Then said the king to the servants, Bind him hand and foot, and take him away, and cast him into outer darkness; there shall be weeping and gnashing of teeth.” Mt. 22:11-13
Heaven is only for those who put on Christ.
