And Ittai answered the king, and said, As the LORD liveth, and as my lord the king liveth, surely in what place my lord the king shall be, whether in death or life, even there also will thy servant be. 2 Samuel 15:21

David was now forsaken of everybody. His faithful bodyguard was all that he had on earth to depend upon, and then it was that Ittai cast in his lot with David. Now beloved, it is very easy to follow religion when she goes abroad in her silver slippers, but the true man follows her when she is in rags, and goes through the mire and the slough. To take up with Christ when everybody cries up His name is what a hypocrite would do, but to take up with Christ when they are shouting, “Away with Him! away with Him!” is another matter. There are times in which the simple faith of Christ is at a great discount. At one time imposing ceremonies are all the rage, and everybody loves decorated worship, and the pure simplicity of the gospel is overloaded and encumbered with meretricious ornaments; it is such a season that we must stand out for God’s more simple plan and reject the symbolism which verges on idolatry and hides the simplicity of the gospel.

At another time the gospel is assailed by learned criticisms and by insinuations against the authenticity and inspiration of the books of Scripture, while fundamental doctrines are undermined one by one, and he who keeps to the old faith is said to be behind the age, and so on. But happy is that man who takes up with Christ, and with the gospel, and with the truth when it is in its worst estate, crying, “If this be foolery, I am a fool, for where Christ is there will I be; I love Him better at His worse than others at their best, and even if He be dead and buried in a sepulchre I will go with Mary and with Magdalene and sit over against the sepulchre and watch until He rise again, for rise again He will; but whether He live or die, where He is there shall his servant be.” …Happy shall ye be! Your loyalty shall be proven to your own eternal glory. Ye are soldiers such as He loves to honor. ~ C.H. Spurgeon
