Alma Ch32

As the missionaries spread around to teach the Zoramites, they found that the poor were most accepting of their message and were humbled and ready to listen to the message. Alma teaches them about faith, hope, ministering angels, and how they can nourish their new found knowledge and faith into a blossoming tree to pick the fruit of eternal life from.
The missionaries preached to everyone, but only the poor that were cast out of the synagogues (churches) for not being good enough and not allowed to worship listened to their message (v1-4). The were humbled and all gathered to hear the words that answered their desire to know how they were to worship God because they aren't allowed in the churches, and the answer was that they can worship anywhere and anytime (v5-12). Alma taught they they need to humble themselves enough to repent of their sins before the Lord without needing to be chastened by the Lord first (v13-16). But don't be worried if you were someone who needed to be humbled because I was.
Many people are stubborn and ask for a sign, but that isn't faith because you'll just know and not believe (v17-19). To have faith, which is essential to gaining salvation, you can't know for sure first, but you must hope for things which aren't known which are true (v20-21). There have been many signs from angels, prophets, and yet the Lord still often needs to humble us like he has the poor of the Zoramites to be ready to receive the knowledge of God like a planted seed (v22-26). This seed that is planted is faith because it has the potential to be a perfect knowledge of the truth if it is taken care of properly, and as it grows your faith will Swell within your breast, Enlarge your soul, Enlighten your understanding, and become Delicious to you (v27-28). I don't know if you got that but it stands for SEED :)
As a seed is nourished and begins to grow, it becomes stronger just like faith is strengthened if nourished, and as long as you feed a good seed, it will grow into a good plant or tree in this certain analogy (v29-33). Once you have nourished your faith and helped it form into a perfect knowledge can you just leave it be? No, you must always exercise your faith to keep the muscles strong and durable (that's right I switched analogies on ya there a little) to protect you from the devil (v34-37).
Back to plants, it is important to have good roots for a tree to survive many years and if it is neglected those roots will wither away from your barren ground; why can't you just water it (v38-39)? Only a nourished tree can bring forth the fruit of the tree of life; nourished with diligence, faith, and patience (v40-41). With those, the tree will bring forth fruit that is most precious above all else because it is eternal life which is the reward for all your hard work nourishing your faith (v42-43).
