We have often been told that "faith without works is dead" (James 2:20) . I had heard that all growing up, but it was not until I was with Sister Dudding that it really became clear what that meant. And its significance is soooooo simple! All it takes is common sense!
The example President Maluenda used:
If I want to lose weight, I might exercise faith by praying to God for help losing it. If I pray, but just continue to sit around eating cake and ice cream every meal, am I going to lose any weight? No, of course not! But if I pray for help, and I exercise every day and watch what I eat, I'm going to lose weight. God will help me perhaps have the willpower to do it, but it's up to me to take the first steps.
So, in the mission field: if we pray to find investigators, but we don't open our mouths on the street, we won't find them!
For all you regular members: if you pray to have a stronger testimony, but you don't read the scriptures, pray every day, and go to church, you're not going to get a stronger testimony. You may have a strong belief and even knowledge that prayer works, and yes, prayer is an act of faith. But after that prayer, it is up to us to take the next step. We can't just wait around for things to happen.
It sounds simple and like common sense, right? But if you really try to apply this concept in any and EVERY aspect of your life, you will see that acting on faith really IS an act of faith.
