If you're like me you've tried to search for something on LDS.org, but with little success. Recently I stumbled on this topical arrangement of gospel principles and have found it handy. It's great for FHE preparation, preparing a talk or lesson, or just for personal study.
First you go to LDS.org. In the top menu mouse over Gospel Library and find Gospel Topics, the 3rd item from the top.
Then you use the alphabet to find your topic. For example tomorrow's lesson is on Forgiveness. Let's see what's there.
Click on Forgiveness and see a simple definition and several expandable sections beneath...Additional Information, Scripture References, Church Magazine Articles, and Additional Online Materials.
Click on a section to open it. You'll find a wealth of information, but not a "glut". They know that you have limited time and want the best resources and quotes. So, they've made it easy to get right to the most focused material.
Don't spend a lot of time hunting for the best talks, scriptures, or quotes on a gospel topic. Take a few minutes to familiarize yourself with this great resource. It will come in handy.
