the same person

Henry B. Eyring: You weren't the same person [after serving] because the Atonement of Jesus Christ is real. And the promise is real that we can become new, changed, and better. And we can become stronger for the tests of life. We then go in the strength of the Lord, a strength developed in His service. He goes with us. And in time we become His tested and strengthened disciples.
