[Sidenote: A review.] Let us stop now for a moment and think before we proceed to the special subject of this chapter. It is clear, from what we have learned, that Jesus had a very specific mission to perform on the earth. He did not come merely to display miraculous power. He came to save mankind--to teach them to know God and His commands, and to show them, further, how to keep the commands. And the wonderful thing about the mission of Jesus is that He was willing to suffer as no other man has ever suffered and finally to lay down His life in order to bring about the purpose of God. And the great purpose of God in this world is to bring to pass the immortality and eternal life of man. For just as Jesus did not come merely to show how He could perform wonders, so God did not organize the earth and put living things upon it only to display His power. He had a far greater and higher purpose. That the purpose may be accomplished, man must learn to know God and Jesus Christ whom He hath sent. [Sidenote: The problem of evil.] Now, it may seem to you that, if God were so desirous of saving mankind that He was willing to give His only Begotten Son to accomplish the desire, He could have made it very easy for men to keep His commands. Indeed, He might have made His will the only possible thing to do. But it is not so. It is not ever really difficult to keep the commands of God if one sets his mind to keep them; but there are always so many other things {56} possible to do that one is tempted to neglect the word of God. Evil is always in the way. We wonder why there should be evil in the way, and how evil came to be. Men have wondered about the same thing for many ages. It would be so much easier to be good if there were no wrong. In this lesson, therefore, we want to learn how evil came into the world; in the next one, we shall learn why it is here. [Sidenote: The parable of the sower.] One day, when a great multitude of people had assembled about Him, Jesus related the parable of the sower. Said He, "A sower went out to sow his seed: and as he sowed, some fell by the wayside; and it was trodden down and the fowls of the air devoured it. And some fell upon a rock; and as soon as it was sprung up, it withered away, because it lacked moisture. And some fell among thorns; and the thorns sprang up with it, and choked it. And other fell on good ground, and sprang up, and bare fruit an hundredfold.... [Sidenote: The meaning.]
