And those indeed that they may receive a corruptible crown, but we an incorruptible.&#8221; In the Gospel according to Matthew: &#8220;Every tree that bringeth not forth good fruit shall be cut down, and cast into the fire.&#8221; Also in the same place:&#160; &#8220;Many shall say unto me in that day, Lord, Lord, have we not prophesied in Thy name, and in Thy name have cast out devils, and in Thy name have done great works? And then shall I say to them, I never knew you; depart from me, ye who work iniquity.&#8221; Also in the same place: &#8220;Let your light shine before men, that they may see your good works, and glorify your Father which is in heaven.&#8221; Also Paul to the Philippians: &#8220;Shine as lights in the world.&#8221;
