Help the children stay away from sin by contrasting sin and the will of God. Show them that some sin may appear to bring happiness and satisfaction, but in reality it robs God’s children of joy, power and ultimately brings heartache. On the other hand, obediance to God’s will brings joy, strengthens the believer and brings a closer communion with the Lord he loves.Romans 2:4,5 says, “Or do you despise the riches of His goodness, forbearance, and longsuffering, not knowing that the goodness of God leads you to repentance? But in accordance with your hardness and your impenitent heart you are treasuring up for yourself wrath in the day of wrath and revelation of the righteous judgement of God.” (Italics mine.)
In your teaching, help the children understand this by demonstrating with examples, illustrations and object lessons the stark contrast between sin and it’s consequences and obediance to God and it’s blessings. Magnify both the desireableness of righteousness and the repulsiveness of sin. Let the wonder of His goodness draw them and the ugliness of sin repel them.
