Except I shall see in His hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into His side, I will not believe. – John 20:25

Dear friends, if you began to seek signs, and if you were to see them, do you know what would happen? Why, you would want more; and when you had these, you would demand still more. Those who live by their feelings judge of the truth of God by their own condition. When they have happy feelings, then they believe; but if their spirits sink, if the weather happens to be a little damp, or if their constitution happens to be a little disordered, down go their spirits, and, straightway, down goes their faith. He that lives by a faith which does not rest on feeling, but is built upon the Word of the Lord, will remain fixed and steadfast as the mount of God.

If you read a story of a person who saw a vision, or if you hear another declare that a voice spake to him-believe those things, or not, as you like; but do not desire them for yourself. These wonders may, or may not, be freaks of the imagination. I will not judge; but we must not rely upon them, for we are not to walk by sight, but by faith. Rely not upon anything that can be seen of the eyes, or heard of the ears; but simply trust Him whom we know to be the Christ of God, the Rock of our salvation.~ C.H. Spurgeon
