Mosiah 7:33

"But if ye will turn to the Lord with full purpose of heart, and put your trust in him, and serve him with all diligence of mind, if ye do this, he will, according to his own will and pleasure, deliver you out of bondage."

When we are faithful and keep the commandments and covenants we have made, the Lord gives us protection. He has the power to deliver us from our hard times and struggles. We just need to do our part and ask.
