Hebrews 11 is called the Faith Hall of Fame because it features a list of many Old Testament heroes who accomplished mightiness by faith.
Studying Hebrews 11 to see how faith works, it will work the same for us as it did for them.
We may not do the same exploits as they did, but God desires to do things in us that pertain to these times that we live today.
The principles of faith will work just the same as they did for them when we work them properly.
