20 And when the Jews heard these things they were angry with him; yea, even as with the prophets of old, whom they had cast out, and stoned, and slain; and they also sought his life, that they might take it away. But behold, I, Nephi, will show unto you that the tender mercies of the Lord are over all those whom he hath chosen, because of their faith, to make them mighty even unto the power of deliverance.

If I have faith then the Lord will help make me overcome my trials.
The Lord's tender mercies are over all those who he chooses. He chooses them because of their faith. Tender mercies in my opinion are like God smiling down on our valiant efforts and giving us a little break. Sending some extra help. I remember a story in the Book of Mormon where some people were in bondage, times were tough. They were not free to worship God. They had been told not to pray so they prayed in their hearts. Because of their faith, God made their burdens feel light. He didn't take away their burdens, he didn't rescue them from bondage, he just gave them more strength to face their burdens with energy and patience. Then the time came when the time was right and they were able to be delivered from bondage. It seems the key to it all is having faith, not just wimpy faith like a mere belief but a powerful strong faith that moves, breathes and acts.
