The LDS Church recently released a video that perfectly summarizes what the Church is all about:
That is what it means to be a Mormon – that is what it means to be Christian.
Another video that explains what “Mormonism” is all about is this one on the new Mormon.org website: http://mormon.org/me/1MQC-eng
That is the gospel of Jesus Christ. We can learn and spout of theology and scriptures all day but without repentance and forgiveness – without the Atonement, the grace, of Jesus Christ – our religion and our lives would mean very little. Those two videos demonstrate the power of Jesus Christ working in people’s lives.
