When Jesus was upon the earth vast multitudes attended Him. Where He went they followed. But now when Jesus is no longer bodily present upon the earth, when we cannot see Him with our natural eyes, we speak of walking by faith, and you may be curious to know what is meant by walking by faith. I think that I can illustrate it in this way: Here is a sheet of writing paper. Now above the writing paper I will place this magnet, and then below it I will place this small bit of iron. The attracting power of the magnet holds the iron up against the paper. Now, when I move this magnet on the upper side of the sheet from place to place, you will observe that this little piece of iron on the lower side of the sheet goes in the same direction. It follows the magnet very closely. The paper is between them. Now, if this paper were enlarged so as to be as long and as broad as the ceiling of this room, of course you would not be able to see the magnet. It would be hidden from your view. But as you would move the magnet from place to place, the little iron below would continue to follow it. So Jesus Christ is no longer visible; we cannot see Him with our natural eyes, but He draws the Christian who is in this world, and so the Christian follows Him. He walks in the footsteps of the Lord Jesus. And it is on that account that we say that the Christian walks by faith, and not by sight. Just before Jesus was crucified He said: "And I, if I be lifted up from the earth, will draw all men unto Me." (John xii: 32.) So He draws you and He draws me. And so also by His love He would draw every person in all the world to Him. Let us not resist the drawings of the Holy Spirit, but come to the Lord Jesus Christ and love Him with our whole heart. QUESTIONS.--What can the magnet do? Can the power of the magnet be seen? Can the magnet lift as many nails as tacks? Are old rusty nails drawn by the magnet? Who are like the little tacks? Who are like the small nails? Who are like the rusty nails? Does everybody desire at times to be good? What draws them in the right direction? Can we see the power that causes us to desire to be good? What is the name of the power or force that causes the nails to fall from the magnet? What power draws people from doing right? Should we always yield to the power that draws us in the right direction? Does Christ have to be seen in order to accept His influence? [Illustration: Daniel in the Lion's Den.] KEYS.
