When a fire starts burning a house, it becomes clear whether the builders used materials in their work that will burn, or materials that will not burn. Similarly [MET], when God judges us, it will be clear whether we taught others things that were long-lasting and valuable or not. If the materials that are used to build a house are materials that do not burn, the builder will receive a reward [MET]. Similarly, if we have taught others things that are valuable and long-lasting, God will give us a reward.
