The deep things of God cannot be discovered by unaided reason. "Eye hath not seen:" they are not to be apprehended by the artistic vision. "Ear hath not heard:" they are not unveiled amid the discussion of the philosophic schools. "Neither hath entered into the heart of man:" even poetic insight cannot discern them. All the common lights fail in this realm. We need another illumination, even that provided by the Holy Spirit. And the Spirit is offered unto us "that we might know the things that are freely given to us of God."
And here we have the reason why so many uncultured people are spiritually wiser than many who are learned. They lack talent, but they have grace. They lack accomplishments, but they have the Holy Ghost. They lack the telescope, but they have the sunlight. They are not scholars, but they are saints. They may not be theologians, but they have true religion. And so they have "the open vision." They "walk with God," and "the deep things of God" are made known to their souls.
We must put first things first. We may be busy polishing our lenses when our primary and fundamental need is light. It is not a gift that we require, but a Friend.
