The Three Rs of Choice - President Thomas S. Monson

Brethren, you are of a noble birthright. Eternal life in the kingdom of our Father is your goal. Such a goal is not achieved in one glorious attempt but rather is the result of a lifetime of righteousness, an accumulation of wise choices, even a constancy of purpose. As with anything really worthwhile, the reward of eternal life requires effort.
