And Philip ran thither to him, and heard him read the prophet Esaias, and said, Understandest thou what thou readest? And he said, How can I, except some man should guide me? – Acts 8:30-31

When a man’s soul is renewed he begins to think, and he desires to understand many things which aforetime were indifferent to him. He meets with that most plain and precious truth, that “Jesus Christ came into the world to save sinners,” and he is well satisfied with that declaration. Still, as he grows, he seeks more knowledge, and longs to understand the deep things of God…I have known people stumble over hard texts. “What means this text? What means that passage? What means the other Scripture?” You would be astonished if you knew how many people are disturbed in mind, lie awake at nights, and are likely to lose their faith in Christ, over Scriptures which are as cheering as can be when once they are understood. These people need that some man should guide them; for, like the Ethiopian nobleman, they will not otherwise understand what they read. There are to be found, here and there, thoughtful persons, not yet fully instructed in the faith, who are puzzled and confounded as the infinite glory of revealed truth opens up before their astonished gaze. They will know hereafter; but for the present they are sorely troubled and perplexed, and their cruel enemy rejoices that “They are entangled in the land.” Nothing contributes more to this than the divisions in the Christian church. One preacher cries up one thing, and another quite the contrary, till young converts cry, “Which are we to believe?” and they stand as if they had come to cross-roads, and did not know which way to take. I am sorry it should be so; but there is a promise to the family of faith, “All thy children shall be taught of the Lord.” You shall not lose your way if you will accept the Word of God as a little child. Be of good courage; for it is written-“He shall guide thee continually.” ~ C.H. Spurgeon
