This year’s Relief Society theme is all about Belonging. The promise of Relief Society is that we can become a Zion Society. Our job as Relief Society sisters is to encourage one another. 

When we look at one another from an eternal perspective, we can see each one as an eternal sister. We are happy for one another’s successes, we share one another’s sorrows, we forgive one another’s mistakes, and we strengthen one another in our weakness. We may not be perfect at it, but all the Lord requires is that we start by having a heart that is willing (see Doctrine and Covenants 64:34). As we are “willing to bear one another’s burdens,” as we are willing to “mourn with those that mourn” and “comfort those that stand in need of comfort,” as we are willing to “stand as witnesses of God” (Mosiah 18:8–9), we are keeping our covenants with Him.
