And to whom did He swear that they would not enter His rest, but to those who did not obey?…Let us therefore be diligent to enter that rest, lest anyone fall according to the same example of disobedience. -Hebrews 3:18; 4:11

Recollect, your race is win or lose-death or life, hell or heaven, eternal misery or everlasting joy. What a stake that is for which you run. If I may so put it, you are running for your life; and if that does not make a man run nothing will. Put a man there on yonder hill, and put another after him with a drawn sword seeking his life, If there is any run in him you will soon see him run; there will be no need for us to shout out to him, “Run, man, run” for he is quite certain that his life is at hazard, and he speeds with all his might-speeds till the veins stand like whipcords on his brow, and a hot sweat runs from every pore of his body-and still flees onward. Now, he looks behind, and sees the avenger of blood speeding after him; he does not stop; he spurns the ground, and on he flees till he reaches the city of refuge, where he is safe. Ah! if we had eyes to see, and if we knew who it is that is pursuing us every day of our lives, how we should run! for lo! O man, hell is behind thee, sin pursues thee, evil seeks to overtake thee; the City of Refuge has its gates wide open; I beseech thee, rest not till thou canst say with confidence, “I have entered into this rest, and now I am secure, I know that my Redeemer liveth.” And rest not even then, for this is not the place for rest; rest not until thy six days work is done; and thy heavenly Sabbath is begun. Let this life be thy six days of ever-toiling faith. Obey thy Master’s commandment; “labour therefore to enter into this rest,” seeing that there are many who shall not enter in, because, through their want of faith, they shall not be able. If that urge not a man to speed forward, what can? ~ C.H. Spurgeon
