Jesus promised His disciples: “The Comforter, which is the Holy Ghost, whom the Father will send in My name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.” John 14:26. But the teachings of Christ must previously have been stored in the mind in order for the Spirit of God to bring them to our remembrance in the time of peril. “Thy word have I hid in mine heart,” said David, “that I might not sin against Thee.” Psalm 119:11.

All who value their eternal interests should be on their guard against the inroads of skepticism. The very pillars of truth will be assailed. It is impossible to keep beyond the reach of the sarcasms and sophisms, the insidious and pestilent teachings, of modern infidelity. Satan adapts his temptations to all classes. He assails the illiterate with a jest or sneer, while he meets the educated with scientific objections and philosophical reasoning, alike calculated to excite distrust or contempt of the Scriptures. Even youth of little experience presume to insinuate doubts concerning the fundamental principles of Christianity. And this youthful infidelity, shallow as it is, has its influence. Many are thus led to jest at the faith of their fathers and to do despite to the Spirit of grace. Hebrews 10:29. Many a life that promised to be an honor to God and a blessing to the world has been blighted by the foul breath of infidelity. All who trust to the boastful decisions of human reason and imagine that they can explain divine mysteries and arrive at truth unaided by the wisdom of God are entangled in the snare of Satan.
