I think that the big, over-arching theme that I picked up on from reading the Book of Mormon in 2018 and studying it now with these questions is that the words for God are purposefully a little bit overlapping and ambiguous as to which member of the godhead is being referenced. See this post, and probably a good seven or eight others (but that one is the one in which I finally started to feel a little bit of resolution about this topic).

Nephi is talking to his people. He promises them that the Gentiles who repent are the covenant people of the Lord, and that Jews who do not repent will be removed from the covenant. He is explicitly telling his people that the covenant is with people who repent and believe in Jesus Christ, the Holy One of Israel. (2 Nephi 30:2)

The covenant is made between Heavenly Father and us, his children. Jesus Christ is part of the covenant because he is the mechanism, the bridge - the thing that makes the covenant possible.

Answer:
All over the place.

The scriptures are often ambiguous about general words for deity, like "God" and "the Lord" and that probably has more to do with the idea that their purpose, plan, and actions are completely united. Together they work as one God.

I know that Heavenly Father is real. I know that the scriptures witness of him and his son, and that they are true. My knowledge comes through a witness from the holy ghost in both my mind and my heart. It is a feeling, but it is nothing like the other kinds of fleeting feelings and emotions that often seem to plague me. It is steady, sure, deeply hopeful, and real.
