Before next Sunday, do one concrete thing that reflects your sustaining vote: pray specifically for President Oaks or another General Authority by name, or follow through on something you've been prompted to do that you've been putting off.
President Christofferson expressed that the leaders are 'grateful for your faith and prayers in our behalf', implying that our sustaining is a form of faith that blesses both the leaders and those who offer it.
Your witness: Share what the solemn assembly meant to you personally, not what you think it should mean, but what it actually stirred in you when you watched it or participated in it.
