Ether 12:4

Wherefore, whoso believeth in God might with surety hope for a better world, yea, even a place at the right hand of God, which hope cometh of faith, maketh an anchor to the souls of men, which would make them sure and steadfast, always abounding in good works, being led to glorify God.

Belief in God leads to faith, which leads to hope. The hope of our faith is to return to God and live with him forever. Such hope becomes an anchor that holds us fast to God. If we want to live with him in the better world to come, would we not want to do all we can in this life to draw close to him? Would we not want to be like him in every way we can, our mortal limitations notwithstanding? If so, then we would want surely to do his works, which are, of course, good works. If we are going to be comfortable in his presence, we must learn to do what he does, think what he thinks, and want what he wants. We do good things as a natural outcome of acquiring godly attributes. We do good works not so others think we are great but so they realize God is great.

Alma 7:27

And now, may the peace of God rest upon you, and upon your houses and lands, and upon your flocks and herds, and all that you possess, your women and your children, according to your faith and good works, from this time forth and forever. And thus I have spoken. Amen.

The peace Alma promises is a gift from God, for which we qualify through a combination of faith and good works. It comes not from either alone, but from the two attributes working together in us. Faith moves us to good works, and good works builds our faith. With both oars in the water we row a straight course toward God.

Mosiah 5:15

Therefore, I would that ye should be steadfast and immovable, always abounding in good works, that Christ, the Lord God Omnipotent, may seal you his, that you may be brought to heaven, that ye may have everlasting salvation and eternal life, through the wisdom, and power, and justice, and mercy of him who created all things, in heaven and in earth, who is God above all. Amen.

Steadfast and immovable--powerful concepts about faith. We can develop an unshakable testimony when we are determined to follow Christ. "To abound" is to exist in large amounts. So as our faith becomes steadfast, we should do many good works, which means lots of service. When we do these things, Christ will seal us to him. Remember, when we take his name upon us, it is like being in Christ's family. We become his children. Christ will seal us to him when we are faithful to him. Nevertheless, despite all our good works, which Christ appreciates, he brings us to heaven; we don't take ourselves there. We cannot get there without him. But when we join his family and are sealed to him, he will take us to his home to be with his Father and our Father. Only he can do that for us.
