When we speak of gathering Israel on both sides of the veil, we are referring, of course, to missionary, temple, and family history work. We are also referring to building faith and testimony in the hearts of those with whom we live, work, and serve. Anytime we do anything that helps anyone—on either side of the veil—to make and keep their covenants with God, we are helping to gather Israel.
President Russell M. Nelson, "Let God Prevail", General Conference, October 2020
Sometimes I think that if I'm not actively converting someone else to the church and gospel then I'm not doing enough to gather Israel. Or, if I don't go to the temple often and frequently, then I'm not gathering Israel. That worries me at times.
But...after reading these words from a prophet of God, I'm at peace with that. Anytime I do "anything" to help others build testimony or make and keep covenants, then I'm gathering Israel. And I assume as part of helping others this, that could be as simple as just being a good example to help another be better. Maybe my testimony can help another strengthen their testimony. We'd be surprised at what influence we have over another.
Now, that doesn't mean that just focusing on my testimony is sufficient. Or maybe it is. But, my point is, I can't use that as an excuse to be lazy and not actively help another too, through service, through temple attendance, through proclaiming the gospel, etc.
There are things that I cannot do. But there are so many things that I can do to help build the faith of another or even my own faith. After all, isn't working on myself also gathering Israel?
So I need to "Hear Him" and listen as He tells me how to build that faith in others and in myself.
