Jesus Christ said, “Greater love hath no man than this, that a man lay down his life for his friends” ( John 15:13 ). This doesn’t mean we have to die to show our love for our friends. We lay down our lives every time we put someone else’s needs before our own. (And the “friends” mentioned in the scripture above can be understood to be everyone we meet, since Jesus also commanded us to “love one another.”)
We lay down our lives through service. Church members have many opportunities to serve. We can do small acts of kindness for our neighbors, take part in community service, fulfill responsibilities within our local congregations or contribute to the Church’s large-scale humanitarian efforts. These actions, whether great or small, let us feel the happiness of connecting with our brothers and sisters and remind us that God often allows us to be the answer to someone else’s prayers.
