An object lesson is a convincing demonstration of a principle or ideal. Object lessons are extremely valuable teaching tools provided they are simple, clear, and memorable. When Jesus used the object lesson of the farmer and the different types of ground in Matthew 13:1-23, He achieved all three objectives. The simplicity is obvious to anyone who lives in an agricultural world that the environment determines whether growth is effective or not. The lesson was clear in that there are no distractions or complicated nuances to the simple work of planting and growing seeds. The exercise is memorable because people daily were engaged in farming. But even as the students can learn and remember objective lessons well, it may be better to invite them to think of their own ways to offer a convincing demonstration of a principle or ideal. inviting them to develop their own heightens the learning experience.
