But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. – 1 Corinthians 2:14

If you were to go to some remote island where beauty consisted in having one eye and a twisted mouth, and a sea-green complexion, you would say, “Those people are strange beings.” Such are the people of this world; spiritual beauty is not appreciated by them. This world appreciates the man who makes money, however reckless he may be of the welfare of others while scheming to heap up riches for himself. As for the man who slays his fellow-creatures by thousands, they mount him on a bronze horse, put him on an arch, or they pile up a column, and set him as near heaven as they can. He slew his thousands: he died blood-red: he was an emperor, a tyrant, a conqueror; the world feels his power and pays its homage. As for this Jesus, He only gave His life for men; He was only pure and perfect, the mirror of disinterested love. The vain world cannot see in Him a virtue to admire. It is a blind world, a fool world, a world that lieth in the wicked one. Not to discern the beauties of Jesus is an evidence of terrible depravity. Have you, my dear friend, frankly to confess that you were never enamoured of Him who was holy, harmless, and undefiled, and went about doing good? Then let this come home to you-that the question is not as to whether Christ is lovely or not, the mistake is here-that you have not a spiritually enlightened eye, a fine moral perception, nor even a well-regulated conscience, or you would see His loveliness at once. You are dark and blind. God help you to feel this.

Do you not love Christ? Then let me ask you why you do not? There was never a man yet that knew Christ that could give a reason for not loving Him, neither is there such a reason to be discovered. He is altogether lovely. In nothing is He unlovable. Oh I wish that the good Spirit of God would whisper in your heart, and incline you to say, “I will see about this Christ. I will read of Him. I will look at the portraits of Him painted by the evangelists, and if He be indeed thus lovely, no doubt He will win my heart as He appears to have won the hearts of others.” I pray He may. ~ C.H. Spurgeon
