The simplicity of faith puzzles people; they worry their brains to understand, when they ought to yield up their hearts to receive. The reception of the truth is like a boy receiving a watch as a present: he understands nothing of the movements within; all he knows is that it is useful and almost every man has one, so he accepts it with delight. Future investigation enables him to comprehend the works, and how to regulate it.
So it is with God's Word—it has to be accepted by faith. Reception of it brings with it an understanding of God's principles, and an awakening to the responsibilities connected with it, and a delight in accepting them.
