I grew up in the 80's and Marty McFly was a household name. He was the main character played by Michael J. Fox in the hit movie Back to the Future. There is a scene where a picture of him of him and his siblings start fading because it looks like history has been changed, and his parents might not get together.
After being released as a counselor in the bishopric I was called as the ward mission leader in the Highland 14th ward. I was asked to present a ward mission plan. The theme that I felt inspired to use was simply, "As I have loved you, love one another."
