Now, boys and girls, this worm represents sin in the human heart, or wickedness possibly presents the thought better, and when you see a boy or girl doing wrong, they are simply giving outward expression to the wickedness which exists in their hearts. Boys are bad, not so much because the influences by which they are surrounded are bad, but because their hearts are sinful, and wicked, and bad. But I am sure that you will want to know how wickedness gets into the human heart. I will tell you how it is. Way back in the spring-time of the history of the human race, way back in the Garden of Eden, soon after God had created Adam and Eve, Satan came and inspired in the hearts of these first people the desire to disobey God. God told Adam and Eve that they should not eat of the fruit of the forbidden tree, and that when they did they would die, that is, they would be separated from God. Satan came and told them that they would not die, but that when they ate of the fruit of this tree they would become very wise. They believed Satan rather than God, and they did that which was wicked and wrong. And so throughout all the generations since, there has been that willingness to believe Satan and to do what he wants us to do, rather than to believe God and do what God would have us to do. Boys and girls who find themselves inclined to disobey their father or mother, to be disrespectful to those who are older than they, to do wrong on the Sabbath, to remain away from the Sunday-school and church, and to enjoy the beautiful spring-day, by strolling through the fields or wandering through the woods, do so, not alone because the day is pleasant or because of the opportunities from which others turn away, but because there is wickedness in their hearts. So when boys quarrel and fight, or steal, or do any other thing that is wrong, it is not so much the influences by which they are surrounded, the temptation from without, but the wickedness and the evil and the sinfulness which there is in the human heart, eating its way out through their heart into their lives, and deforming their lives, which otherwise would be upright, honorable and manly and Christ-like. I trust that when you are tempted to do wrong you will recognize the fact that there is evil in your heart, and that you will go to Jesus and earnestly pray Him to take away this evil out of your heart, and to give you a new, clean heart. Just the same as with these apples, if you had the privilege of choosing, I am sure you would prefer the large one, which has not been spoiled because of the destructive worm inside, so I trust you will choose to have the good heart, which God can give you, rather than the heart that has wickedness and sin within. If you will go to God in prayer and ask Him, He will give you a good heart, a true heart, one that has no sin and no wickedness within.
