I've been asked recently "How do you not lose faith?" Here's my reply:
Some days having faith is easier than others for sure!
But when I can push the bad thoughts and worries out of my mind and know that I am doing everything possible in my power to be worthy of the blessings the Lord thinks I deserve it makes my trials easier to bear.
I will follow the Lord no matter what or how horrible life seems because in doing so I know and have peace that at least I'm doing the best I can in hopes of deserving the best the Lord has.
"Beareth all things, believeth all things, hopeth all things, endureth all things."
"And moreover, I would desire that ye should consider on the blessed and happy state of those that keep the commandments of God. For behold, they are blessed in all things, both temporal and spiritual; and if they hold out faithful to the end they are received into heaven, that thereby they may dwell with God in a state of never-ending happiness. O remember, remember that these things are true; for the Lord God hath spoken it."
- Mosiah 2:41
