A verse jumped out at me this morning. In Alma 15:18, we read that Alma takes his friend Amulek into his own house in Zarahemla after Amulek leaves his house in Ammonihah:
18 Now as I said, Alma having seen all these things, therefore he took Amulek and came over to the land of Zarahemla, and took him to his own house, and did administer unto him in his tribulations, and strengthened him in the Lord.
Remember in Alma 8:21, when the roles were reversed?
20 And the man said unto him: I am a Nephite, and I know that thou art a holy prophet of God, for thou art the man whom an angel said in a vision: Thou shalt receive. Therefore, go with me into my house and I will impart unto thee of my food; and I know that thou wilt be a blessing unto me and my house.
21 And it came to pass that the man received him into his house; and the man was called Amulek; and he brought forth bread and meat and set before Alma.
22 And it came to pass that Alma ate bread and was filled; and he blessed Amulek and his house, and he gave thanks unto God.
I find this touching and a reminder that each of us take turns in mortality serving others and being served by others.
