Yesterday, we had a 'fireside' that the ward council decided we needed to give at a meeting we weren't invited to. We had nine members show up. One of them was the ward mission leader who was helping to provide the technology, and one of them was on the bishopric. It was a good fireside though. We talked about how the members can use technology to share the gospel with their friends. We showed them some videos from an address Elder Bednar gave at BYU (I think it was BYU). It was really good, you should look it up.
You can watch the whole thing and it is full of good ideas for missionary work, and you should do it because otherwise the entire earth would be wasted at the second coming.(D&C 2) If we don't do missionary work, then we won't have members to perfect, and we won't have their kindred dead to redeem. It is the entire purpose of the church and of our Heavenly Father to share the Gospel (Moses 1:39) so that we can save people. If His purposes aren't accomplished, it just shows that we don't understand the purpose of God's creations. We don't understand the Creation, we don't understand the Fall, and we don't understand the Atonement. So hit 'like.' That's pretty much all it takes now. Watch a mormon message, hit 'like,' and you could save someone.
