Moroni Ch8

It's very clear in the scriptures that baptizing infants is unacceptable because they are alive in Christ through the atonement. As we grow older we have to practice faith, repentance, meekness, and other qualities that children already have so we can receive the Holy Ghost and be lead to salvation through endurance.

This chapter is actually more words of Mormon that were in a letter to Moroni guiding him when he was called to minister (v1). Mormon starts off with showing how glad he is that is son is following The Lord and that he prays for him constantly out of love (v2-3). Mormon heard about some issues going on in the church because people argue whether they should baptize little children, so he writes this letter to help Moroni clear up misconceptions and resolve the problem ASAP (v4-6). These teachings come straight from The Lord, through the Holy Ghost, after Mormon had prayed and asked for guidance (v7-9):

"I, the Redeemer, have come to call the wicked to repentance, not to call the already righteous like little children who are not capable of committing sin because I have taken the curse of Adam from them automatically."

Teach the principle of repentance and baptism to those who are accountable so they can humble themselves like little children who need no repentance not baptism yet (v10-11). If children were not already alive in Christ, then God is partial and allowed many children to go to an endless hell (v12-13). Anyone who thinks children need baptism needs a little faith, hope, and charity in his life because they are trying to pervert the ways of The Lord  (v14-16).

Mormon has a love for little children because of the charity in his heart, and he knows they need no baptism because God is unchanging and does not deny His pure mercies to them (v17-19). As for his opinion about any who still think children need baptism, it's pretty clear he thinks they will be in hell after the final judgment (v20-21). Another way to think about the mercy and love of God is to remember that everyone will get the chance to choose Christ, so those who never got the chance on earth will not be condemned for not knowing better, just like children (v22-23).

As for those who need help, we have guidance from Mormon on what we can do to achieve the salvation that little children already have. First, we repent and be baptized through faith unto the fulfilling of the commandments which brings a remission of sins (v24-25). Next, we become meek, lowly in heart, and humble enough to receive the Holy Ghost as a constant companion until we have endured to the end and can dwell with God (v26). 

The end of the letter gives us a glimpse into the real world because Mormon is off at war, leading the Nephites, and he mentions that they are prideful (v27). Yet he still has hope they will repent because he asks for prayers from Moroni even though he knows they must perish soon because they have lost the Spirit and rejected so great a knowledge of the truth (v28-29). He also doesn't know exactly when he's coming home...so it's just an unknowing farewell (v30).
