In verse 1, Mormon is talking to us- the people of the latter days. He basically says: Hey, I've got a message from you from Jesus. He told me to tell you this.
We should listen and DO!
Verse 2 is the message directly to us from the Savior: Stop doing bad stuff. Repent and come to Me. Get baptized. Then I'll give you the gift of the Holy Ghost and welcome you into the house of Israel.
That pretty much sums up the main message of all the scriptures. He invites us to make the good and righteous choices that would qualify us to receive the greatest of blessings: Eternal life.
