Les Christie writes that a yoke was normally made for two animals. Bearing the yoke expresses the idea of working alongside others who are performing similar tasks and striving for similar goals. Learning to handle burdens, tasks and responsibility helps prepare young people for life. Extrinsic motivation originates from some outside force. Something extrinsic makes the individual respond, such as a punishment or reward.
Intrinsical motivation comes from within.
When someone is intrinsically motivated, they do not need the threat of punishment or the promise of a reward to attend Sunday School, go to GOYA meetings, participate in Bible Studies and develop a personal prayer life. This is the kind of motivation we must strive for in our youth groups. Yes, each child must learn responsibility.
