For if God hath not spared the natural branches, fear lest perhaps he also spare not thee. See then the goodness and the severity of God: towards them indeed that are fallen, the severity; but towards thee, the goodness of God, if thou abide in goodness, otherwise thou also shalt be cut off.
Not every one that saith to me, Lord, Lord, shall enter into the kingdom of heaven: but he that doth the will of my Father who is in heaven, he shall enter into the kingdom of heaven.
Many will say to me in that day: Lord, Lord, have not we prophesied in thy name, and cast out devils in thy name, and done many miracles in thy name?
And then will I profess unto them, I never knew you: depart from me, you that work iniquity.
Know you not that they that run in the race, all run indeed, but one receiveth the prize. So run that you may obtain. And every one that striveth for the mastery refraineth himself from all things. And they indeed that they may receive a corruptible crown: but we an incorruptible one. I therefore so run, not as at an uncertainty: I so fight, not as one beating the air. But I chastise my body and bring it into subjection: lest perhaps, when I have preached to others, I myself should become a castaway.
