1 John 1:1-4
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked on…
Consider what impressions we gain from the sense of touch. It is touch which, more than any other sense, convinces us of the reality of matter. What you see might be merely a phantom, an optical illusion, a picture painted on the retina of the eye, and nothing more; but if you go up to the thing you see, and touch it, and handle it, you become assured of its existence, you know that it is substantial. Now what is faith? It may be defined as the faculty by which we realise unseen things. I say the faculty (not by which we conceive, but) by which we realise these things, feel them to have a body and a substance. To imagine the truths of religion is not to believe them. We may from time to time imagine God as He is in heaven, surrounded by myriads of glorious angels — we may imagine Christ looking down upon us from God's right hand, interceding for us, calling us to account at the last day, and awarding to us our final doom; but the mere picturing these things to ourselves is not the same thing as believing them; the believing them is the having such a conviction of their reality as to live under their influence, and to be in some measure, at least, governed by them. In short, to imagine the truths of religion is like surveying things by the eye; to believe in the truths of religion is like grasping the same things with the hand, and thus proving them to have substance and consistency.
