Alma 26:3

Behold, I answer for you; for our brethren, the Lamanites, were in darkness, yea, even in the darkest abyss, but behold, how many of them are brought to behold the marvelous light of God! And this is the blessing which hath been bestowed upon us, that we have been made instruments in the hands of God to bring about this great work.

Every day we can be an instrument in God's hands for the work he has placed us here to do. We may not convert a nation of Lamanites, but we can teach a child or help a neighbor or ease the burden of someone or lift a spirit or show someone God's love. Each day we can do something wonderful if we listen for God's whisper in our ear and follow his direction.

Alma 14:26

And Alma cried, saying: How long shall we suffer these great afflictions, O Lord? O Lord, give us strength according to our faith which is in Christ, even unto deliverance. And they broke the cords with which they were bound; and when the people saw this, they began to flee, for the fear of destruction had come upon them.

The help and strength we receive from God is in direct proportion to our faith. This is because our faith moves us to action. The bigger our faith, the bigger our actions, and thus the more help we need and the more strength we will use.  God gives us all we can handle, and strong faith enables us to handle heavy things.

Alma 7:11-13

And he shall go forth, suffering pains and afflictions and temptations of every kind; and this that the word might be fulfilled which saith he will take upon him the pains and the sicknesses of his people. And he will take upon him death, that he may loose the bands of death which bind his people; and he will take upon him their infirmities, that his bowels may be filled with mercy, according to the flesh, that he may know according to the flesh how to succor his people according to their infirmities. Now the Spirit knoweth all things; nevertheless the Son of God suffereth according to the flesh that he might take upon him the sins of his people, that he might blot out their transgressions according to the power of his deliverance; and now behold, this is the testimony which is in me.

Many aspects of Christ's atonement are described in these few verses. Christ suffered not only for our sins, but he suffered all things that we experience in mortality. He can help us in our troubles and afflictions because he has experienced them, endured them, and overcome them. He could have learned about us by the power of the Holy Ghost, but he wanted to know us directly so he could even better understand us and help us. He knows every temptation, and he knows how to resist it. He even knows how to overcome death. He is ready, able and willing to help us with everything we face in this life. We have but to ask.

Second Nephi 7:9

For the Lord God will help me. And all they who shall condemn me, behold, all they shall wax old as a garment, and the moth shall eat them up.

No adversary can stand against Christ, for the power of God is in Him. Those who oppose Him will find themselves on the losing side. They will be destroyed. Their cause will fade away, cankered through and through by its own corruptness.
